BMW 5 SERIES G30 & G31 PERFORMANCE PARTS AND STYLING UPGRADES
The BMW 5 Series G30 Saloon and G31 Touring combine executive comfort, modern technology and strong performance potential in a refined everyday package. Produced in pre-LCI form between 2017 and 2020, this generation remains a popular choice for drivers looking to improve exhaust sound, engine response, exterior styling and overall road presence.
Our collection of BMW G30 and G31 performance parts includes carefully selected upgrades for petrol, diesel and plug-in hybrid models. Whether you are creating a clean OEM+ daily driver, enhancing an M Sport vehicle or building a more aggressively modified 540i or M550i, EURO TUNED offers solutions for a wide range of performance and styling goals.
BMW G30 AND G31 MODELS
The pre-facelift BMW 5 Series range includes several engine and drivetrain combinations, meaning compatibility can vary significantly between vehicles. Popular models include:
- BMW 520i G30 performance parts
- BMW 520d G30 and G31 upgrades
- BMW 530i and 530d aftermarket parts
- BMW 530e plug-in hybrid styling parts
- BMW 540i B58 performance upgrades
- BMW 540d diesel performance components
- BMW M550i G30 performance parts
- Rear-wheel-drive and xDrive models
- G30 Saloon and G31 Touring body styles
Parts should always be selected for the exact engine, drivetrain, production year, body style and bumper configuration.
PERFORMANCE UPGRADES FOR THE BMW 5 SERIES G30
The G30 platform responds well to carefully selected modifications designed to improve intake airflow, exhaust flow, cooling and driver engagement. Popular BMW G30 performance upgrades include valved exhaust systems, high-flow downpipes, cold air intakes, turbo inlet pipes, charge pipes, intercoolers and compatible ECU tuning.
The best setup depends on the engine and intended use of the vehicle. Four-cylinder petrol and diesel models require different components from six-cylinder B58 or B57 vehicles, while the V8-powered M550i uses its own model-specific exhaust, intake and cooling hardware.
BMW G30 PERFORMANCE EXHAUST SYSTEMS
A BMW G30 performance exhaust is one of the most effective ways to improve sound and rear-end appearance. Factory exhaust systems are designed around comfort and noise restrictions, while a quality aftermarket system can create a deeper tone, freer exhaust flow and a more engaging driving experience.
BMW G30 valved exhaust systems offer greater control over exhaust volume. With the valves closed, the car can retain a quieter and more refined sound for motorway journeys, residential areas and daily driving. Opening the valves produces a louder and more aggressive exhaust note when stronger performance character is desired.
Available configurations may include:
- Valved cat-back exhaust systems
- Axle-back and rear-section exhaust upgrades
- Resonated and non-resonated systems
- Single-exit, dual-exit and quad-exit conversions
- Exhaust systems for petrol and diesel models
- Polished, black, titanium-style and carbon fibre exhaust tips
The final sound can vary according to the engine, catalytic converters, OPF or GPF filters, downpipes, resonators and engine software fitted to the vehicle.
BMW 540I B58 PERFORMANCE PARTS
The BMW 540i G30 is one of the most popular models for performance tuning thanks to its turbocharged B58 engine. Common upgrades include cold air intakes, high-flow downpipes, charge pipes, intercoolers, performance exhaust systems and compatible ECU software.
A carefully planned BMW 540i B58 performance package can improve airflow, exhaust sound and tuning potential while retaining the comfort and refinement expected from the 5 Series. Components should be matched to the vehicle’s production date, drivetrain and existing modifications.
BMW G30 AND G31 DOWNPIPES
An upgraded BMW G30 downpipe can reduce exhaust restriction after the turbocharger, increase exhaust volume and support additional tuning potential on compatible models. Downpipes are commonly installed alongside an aftermarket exhaust and suitable engine software.
High-flow catted downpipes offer a balance between improved gas flow, stronger sound and everyday usability. Catless downpipes are designed for maximum flow and a more aggressive exhaust note but may not comply with emissions, inspection or public-road regulations in every country.
Downpipe fitment varies between B48, B58, diesel and V8-powered models. Local regulations and software requirements should always be checked before installation.
COLD AIR INTAKES AND TURBO INLET UPGRADES
A BMW G30 cold air intake can enhance induction sound and support more efficient airflow into the engine. Intake systems are especially popular with owners looking for stronger turbocharger sound and a more engaging experience under acceleration.
Depending on the engine, an intake upgrade may replace the original airbox, filter, intake pipework or turbo inlet components. Selected systems feature carbon fibre construction, combining improved airflow with a premium engine-bay appearance.
Turbo inlet and charge pipe upgrades can also reduce restriction and replace selected factory components on compatible vehicles. Fitment with sensors, engine covers and existing modifications should be confirmed before ordering.
INTERCOOLERS AND COOLING COMPONENTS
Turbocharged BMW 5 Series models can benefit from upgraded cooling components designed to manage charge-air temperatures more effectively. A larger BMW G30 intercooler can help maintain more consistent performance during repeated acceleration, spirited road driving or demanding use.
Cooling upgrades are particularly relevant for tuned vehicles running increased boost. Depending on the engine, available components may include intercoolers, charge pipes, auxiliary radiators and supporting airflow upgrades.
BMW G30 CARBON FIBRE PARTS
The executive body lines of the G30 provide an excellent foundation for BMW G30 carbon fibre parts. Carefully selected exterior styling components can create a lower, wider and more aggressive appearance while retaining the premium character of the vehicle.
Popular BMW 5 Series styling upgrades may include:
- BMW G30 carbon fibre front splitters
- Front bumper corner extensions and canards
- BMW G30 side skirt extensions
- Carbon fibre rear diffusers
- Boot lip spoilers for G30 Saloon models
- Roof spoiler extensions for G31 Touring models
- Carbon fibre mirror covers
- Gloss black or carbon fibre kidney grilles
- Carbon fibre exhaust tips and exterior trim
These components can be fitted individually for a subtle OEM+ finish or combined into a complete BMW G30 carbon fibre styling package. Matching the front splitter, side skirts, spoiler and rear diffuser helps create a balanced exterior design.
BMW G30 FRONT SPLITTERS
A BMW G30 front splitter adds definition to the lower bumper and creates a more planted front-end appearance. Available designs range from clean M Performance-inspired additions to larger motorsport-style splitters for more aggressively modified vehicles.
Front bumper design differs between standard, Luxury Line, Sport Line and M Sport models. A splitter developed for an M Sport bumper may not fit a standard bumper without modification, so the complete product compatibility should always be checked.
BMW G30 AND G31 SIDE SKIRTS
BMW G30 side skirt extensions visually lower the side profile and help connect the styling between the front splitter and rear diffuser. They can create a longer and more performance-focused appearance while maintaining the clean design of the vehicle.
G30 Saloon and G31 Touring models may use different mounting points or side skirt dimensions. Products should be selected specifically for the correct body style and production period.
BMW G30 REAR DIFFUSERS AND EXHAUST CONVERSIONS
A BMW G30 rear diffuser transforms the lower rear bumper and enhances the area surrounding the exhaust outlets. Different designs are available for factory exhaust layouts, upgraded exhaust tips and complete dual-exit or quad-exit conversions.
Customers planning an exhaust conversion should choose a diffuser that matches the intended outlet arrangement. Exhaust pipe positioning, mounting points and bumper compatibility must also be considered before installation.
Rear diffuser fitment can vary between petrol, diesel and hybrid vehicles, as well as between standard and M Sport bumpers.
SPOILERS, GRILLES AND EXTERIOR ACCESSORIES
An aftermarket BMW G30 spoiler can improve the rear profile while retaining the premium appearance of the Saloon. G31 Touring models require roof spoiler extensions designed specifically for the estate body style.
BMW G30 gloss black kidney grilles, carbon fibre mirror covers and replacement exterior trim can reduce factory chrome details and create a cleaner, sportier appearance.
These accessories are ideal for owners looking to personalise their BMW without replacing major body panels. They can also be combined with larger carbon fibre parts for a complete exterior transformation.
BMW G30 AND G31 INTERIOR UPGRADES
The cabin can be customised with BMW G30 interior accessories designed to create a more distinctive and driver-focused environment. Depending on product availability, upgrades may include carbon fibre steering wheel trim, extended paddle shifters, replacement steering wheels, gear selector covers and centre-console accessories.
Interior styling components allow owners to continue the exterior carbon fibre theme inside the vehicle while improving the appearance and feel of frequently used controls.
CHOOSING THE CORRECT BMW G30 OR G31 PARTS
Before purchasing BMW G30 or G31 aftermarket parts, it is important to confirm compatibility with the exact vehicle specification. Fitment can vary according to:
- G30 Saloon or G31 Touring body style
- 2017–2020 pre-LCI production period
- Petrol, diesel or plug-in hybrid engine
- Exact engine code and power output
- Rear-wheel-drive or xDrive configuration
- Standard, Luxury Line, Sport Line or M Sport bumper
- OPF or GPF equipment
- Original exhaust outlet configuration
- Existing performance or exterior modifications
Pre-LCI and LCI BMW 5 Series models use different exterior styling and may require different splitters, grilles, diffusers and other body components. Products listed for 2017–2020 vehicles should not automatically be assumed to fit later facelift models.
Always check the complete product title, description and fitment information before ordering. Customers who require additional confirmation can contact EURO TUNED with their model, production year, engine, registration number or VIN.
