Frequently Asked Questions About BMW Performance Parts
Will aftermarket performance parts void my BMW warranty?▸
Under the Magnuson-Moss Warranty Act, a dealer cannot void your warranty simply because you installed aftermarket parts. They must prove that a specific aftermarket part directly caused the failure. We recommend keeping all installation receipts and choosing quality parts from reputable manufacturers — which is exactly what we stock at FFP.
What are the best first modifications for a BMW M3 or M4?▸
The most popular first mods for G80 M3 and G82 M4 owners are a performance intake system (like Eventuri), a catback exhaust for improved sound and flow, and carbon fiber aero pieces (front lip, rear diffuser, trunk spoiler). These bolt-on upgrades deliver noticeable improvements in aesthetics and performance without touching the engine internals.
Are BMW performance parts CARB compliant in California?▸
Some are, some aren't — it depends on the specific part. Intake systems and exhaust components need CARB Executive Order (EO) numbers for street-legal use in California. Carbon fiber exterior parts, suspension, wheels, and brakes do not require CARB certification. Our team can advise on which parts are street-legal for California.
What do BMW chassis codes like F80, G80, and G82 mean?▸
BMW uses internal chassis codes to identify specific model generations. G80 is the 2021+ M3, G82 is the 2021+ M4, F80 is the 2015-2018 M3, G20 is the 2019+ 3 Series, and F30 is the 2012-2018 3 Series. Knowing your chassis code ensures you order parts with exact fitment for your car.
Does Function Factory Performance install BMW parts?▸
Yes — our performance shop at 49 Taylor Court in Thousand Oaks, California offers professional installation for every part we sell. From carbon fiber aero kits to full exhaust systems and suspension setups, our technicians handle BMW builds regularly. Call (805) 267-9762 to schedule.
What is the BMW B58 engine and why is it popular for tuning?▸
The B58 is BMW's turbocharged 3.0-liter inline-six found in the M340i, M440i, X3 M40i, and Toyota Supra. It responds exceptionally well to bolt-on modifications — a quality intake, downpipe, and tune can push the B58 well past 400 horsepower.
Do carbon fiber parts improve BMW performance or just aesthetics?▸
Both. Carbon fiber is roughly 70% lighter than steel and 40% lighter than aluminum. A full carbon fiber aero package can reduce weight by 30-50 pounds, improving acceleration, braking, and handling. Functional aero pieces also generate real downforce at speed.
How long does shipping take for BMW parts orders?▸
Most in-stock BMW parts ship within 1-2 business days. Free ground shipping on orders over $200 typically arrives in 3-7 business days. Expedited shipping options are available at checkout.
