BMW 4 SERIES F32, F33 & F36 PERFORMANCE PARTS AND STYLING UPGRADES
The BMW 4 Series F32 Coupe, F33 Convertible and F36 Gran Coupe combine elegant styling, everyday comfort and excellent modification potential. Produced between 2013 and 2020, the first-generation BMW 4 Series remains a popular platform for drivers looking to improve exhaust sound, engine response, exterior appearance and overall driving character.
Our collection of BMW F32, F33 and F36 performance parts includes carefully selected upgrades for petrol and diesel models, from subtle OEM+ styling components to more aggressive performance modifications. Whether you drive a 420i, 420d, 428i, 430i, 435i, 440i or another compatible 4 Series variant, EURO TUNED offers solutions for daily-driven cars and fully modified builds.
BMW 4 SERIES PERFORMANCE UPGRADES
The BMW 4 Series responds well to modifications designed to improve airflow, exhaust flow and driver engagement. Popular BMW 4 Series performance upgrades include aftermarket exhaust systems, high-flow downpipes, cold air intakes, charge pipes, intercoolers and supporting tuning components.
The most suitable setup depends on the engine, production year, drivetrain and intended use of the vehicle. Parts developed for four-cylinder N20 or B48 engines will differ from upgrades designed for six-cylinder N55 or B58 models, while petrol and diesel vehicles require different exhaust and intake configurations.
BMW F32, F33 AND F36 PERFORMANCE EXHAUST SYSTEMS
A BMW 4 Series performance exhaust is one of the most effective ways to improve the sound and appearance of the vehicle. Factory exhaust systems are designed around comfort and noise restrictions, while a quality aftermarket system can deliver a deeper tone, freer exhaust flow and a more distinctive rear-end design.
BMW F32 valved exhaust systems provide additional control over exhaust volume. With the valves closed, the vehicle can retain a quieter tone for motorway journeys and daily driving. Opening the valves creates a louder and more aggressive exhaust note when a stronger performance sound is desired.
Depending on the model, available configurations may include:
- BMW 420i and 430i performance exhaust systems
- BMW 420d and 430d exhaust upgrades
- BMW 435i F32 performance exhausts
- BMW 440i B58 valved exhaust systems
- Cat-back and axle-back exhaust systems
- Resonated and non-resonated configurations
- Single-exit, dual-exit and quad-exit exhaust conversions
- Polished, black, burnt-style and carbon fibre exhaust tips
Exhaust fitment can vary between Coupe, Convertible and Gran Coupe models, as well as between standard and M Sport rear bumpers. Always check the listed engine, body style and model-year compatibility before ordering.
BMW 4 SERIES DOWNPIPES AND AIRFLOW UPGRADES
A high-quality BMW 4 Series downpipe can reduce restriction after the turbocharger, increase exhaust volume and support additional tuning potential. Downpipes are especially popular for turbocharged 428i, 430i, 435i and 440i models fitted with N20, B48, N55 or B58 engines.
High-flow catted downpipes offer a balance between improved exhaust 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 or road-use regulations in every country. Local requirements should always be checked before installation.
A BMW F32 cold air intake can improve induction sound and support more efficient airflow into the engine. Intake upgrades are commonly installed by owners looking for stronger turbocharger sound, a more engaging acceleration experience and a cleaner engine-bay appearance.
BMW F32 CARBON FIBRE PARTS AND EXTERIOR STYLING
The sculpted body lines of the first-generation 4 Series make it an ideal platform for BMW F32 carbon fibre parts and motorsport-inspired styling upgrades. Carefully selected exterior components can create a lower, wider and more aggressive appearance while retaining the premium character of the original vehicle.
Popular styling upgrades may include:
- BMW F32 carbon fibre front splitters
- Front bumper corner extensions and canards
- BMW 4 Series side skirt extensions
- Carbon fibre rear diffusers
- Boot lip spoilers and larger rear wings
- Carbon fibre or gloss black kidney grilles
- Replacement mirror covers and mirror housings
- Front bumper lips and lower styling additions
- Carbon fibre bonnets and larger exterior panels
- Upgraded exhaust tips and rear bumper accessories
These parts can be installed individually for a clean OEM+ appearance or combined to create a complete BMW F32 carbon fibre body kit. Matching the front splitter, side skirts, spoiler and rear diffuser helps create a balanced design across the entire vehicle.
BMW 4 SERIES FRONT SPLITTERS AND SIDE SKIRTS
A BMW F32 front splitter adds definition to the lower front bumper and creates a more planted road presence. Different designs are available for customers looking for subtle M Performance-inspired styling or a more aggressive motorsport appearance.
BMW F32 side skirt extensions visually lower the side profile and connect the styling between the front and rear of the car. They are particularly effective when combined with a matching front lip and rear diffuser.
Front bumper fitment can vary between standard, Sport, Luxury and M Sport vehicles. Products designed for an M Sport bumper may not fit a standard bumper without additional modifications, so the full product description should always be checked before purchase.
BMW F32, F33 AND F36 REAR DIFFUSERS
A BMW 4 Series rear diffuser transforms the lower section of the rear bumper and gives the car a more performance-focused appearance. Diffusers are available in different exhaust configurations, including single-side dual exit, split dual exit and quad-exit layouts.
Customers planning an exhaust conversion should select a diffuser that matches the intended tailpipe layout. For example, a quad-exit diffuser may require a compatible quad-tip exhaust system or modified rear pipework.
Fitment can also differ between the F32 Coupe, F33 Convertible and F36 Gran Coupe. Selecting a diffuser specifically designed for the correct body style and bumper type is essential for accurate installation.
BMW 4 SERIES SPOILERS AND REAR-END STYLING
An aftermarket BMW F32 spoiler is a simple and effective way to improve the rear profile of the vehicle. Popular options include subtle boot lip spoilers, M Performance-style designs and more pronounced carbon fibre spoilers for aggressively modified cars.
The F33 Convertible and F36 Gran Coupe use different boot-lid shapes from the F32 Coupe, meaning spoilers are not always interchangeable between body styles. Customers should select a product specifically listed for their vehicle.
GRILLES, MIRROR COVERS AND EXTERIOR ACCESSORIES
Smaller styling upgrades can make a noticeable difference to the appearance of the BMW 4 Series. BMW F32 gloss black kidney grilles, carbon fibre mirror covers and replacement exterior trim pieces can remove factory chrome details and create a cleaner, more modern design.
These accessories work particularly well alongside carbon fibre splitters, side skirts and spoilers, allowing owners to build a consistent styling theme without replacing major body components.
BMW F32, F33 AND F36 INTERIOR UPGRADES
The cabin can also be personalised with BMW 4 Series interior accessories designed to create a more driver-focused environment. Depending on product availability, options may include carbon fibre steering wheel trim, extended paddle shifters, gear selector covers, replacement steering wheels and centre-console accessories.
Interior upgrades allow owners to continue the exterior styling theme inside the car while improving the appearance and feel of the controls used on every journey.
CHOOSING THE CORRECT BMW 4 SERIES PARTS
The F32, F33 and F36 share many mechanical and styling features, but not every component fits all three body styles. Compatibility can vary according to:
- F32 Coupe, F33 Convertible or F36 Gran Coupe body style
- Petrol or diesel engine
- Engine code and power output
- Rear-wheel drive or xDrive configuration
- Standard, Sport, Luxury or M Sport bumpers
- Pre-LCI or LCI model year
- Existing factory or aftermarket equipment
- Original exhaust outlet configuration
Before ordering BMW F32, F33 or F36 aftermarket parts, check the complete product title, description and fitment information. Customers who require additional confirmation can contact EURO TUNED with their model, production year, engine, registration number or VIN.
