4.4L twin-turbo V8
Common questions
Which B58 generation does my car have?
The B58 has been through three generations and they are not interchangeable — a Gen 2 part will not fit a Gen 3 car. Model year alone is not a reliable way to tell them apart. Send us your VIN or your chassis code and build date and we will confirm which one you have before you order.
Are these parts covered by a warranty?
Where a part carries a manufacturer warranty we help you make the claim. Details are on the warranty page. Parts sold for off-road and competition use are sold on the understanding that they are not legal for use on pollution-controlled vehicles, and no warranty covers the consequences of using one that way.
How do I know this part fits my car?
Check the fitment table on the product page: it lists the chassis codes, engine codes and model years the part is sold for. If your car is not on it, or the page says the list is still being confirmed, message us with your chassis code, engine code and build date before ordering. A VIN makes it quicker still.
Do I need a tune?
Every product page answers this directly. As a rule, downpipes need a tune and intakes, charge pipes and cooler guards do not. A downpipe on the factory calibration leaves the engine expecting a catalyst that is no longer there, which sets a check engine light and can put the car into reduced power.
What does "off-road and competition use only" mean?
It means the part removes or alters emissions equipment. It is not legal for sale or use on pollution-controlled motor vehicles and it is not CARB certified. Fitting one to a car driven on public roads is the owner's decision and the owner's responsibility. We do not ship these parts to California.
Can I pick up locally instead of paying for shipping?
Yes. Choose local pickup at checkout and no shipping is charged. We are in South Florida and serve Miami-Dade, Broward and Palm Beach. Wait for the ready email before making the trip. Picking up also means we can confirm fitment with you at the counter.
How long does shipping take?
Orders ship from South Florida to all 50 states. Handling and transit times are on the shipping page. Oversized parts move as freight rather than parcel and cannot be delivered to a PO box; where that applies the product page says so and the surcharge appears in the cart before you pay.
