FAQ

How do I know a part will fit my car?

Every listing names the vehicles, years and engines it was made for. Check your car's year, model, trim, engine code (for example K20A2 or K24A2) and transmission against the listing. Swapped or heavily modified cars may need extra parts or a professional's opinion. If you're unsure, email us your year, model, trim, engine and VIN before you order. See our Fitment Help page for a step-by-step guide.

How much is shipping?

We ship within the United States only. Auto parts rates:

Standard: $8
Express: $15
Free Standard shipping on orders of $70 or more

Oversized or heavy items (bumpers, hoods, body kits and similar) may be left out of free-shipping offers or need a freight quote. If an extra charge can't be worked out at checkout, we'll contact you for approval before anything ships. KSeries apparel ships from our print partner at the apparel rates shown at checkout. Your final shipping options and costs always appear at checkout before you pay.

How long will my order take?

In-stock parts ship within 1–3 business days. Many parts ship directly from the manufacturer or distributor. Made-to-order apparel takes 2–7 business days to produce, then ships. Transit time depends on the carrier and the shipping method you choose. If we can't ship within the time we've stated, we'll email you right away with a new estimate. You can then cancel for a full refund. If an item can't ship within 30 days of your order, we'll contact you for your consent before we keep the order open.

Why did my order arrive in more than one box?

We ship parts and apparel from several suppliers and fulfillment locations. An order with items from different sources may arrive in separate packages on different days.

How do I track my order?

Every shipment gets tracking. We email it as soon as each package ships, and each package in a split order gets its own number. You can also check order status in your account. If tracking hasn't arrived within 3 business days of your order, email us your order number.

What if a part is out of stock or on backorder?

If an item you ordered is unavailable or backordered, we'll email you before going ahead. You can wait for the new date, switch to an alternative, or cancel that item for a full refund. Refunds for cancelled items are issued within 2 business days.

Can you special-order a part you don't list?

Often, yes. Email us the part number or a description. Before you pay, we'll confirm the price, lead time and return terms by email. You can cancel a special order for a full refund until the supplier ships it. Once shipped, a special-order part can only be returned if it arrives damaged, defective or wrong.

Can I return a part?

Yes. You have 30 days from delivery to request a return for new, uninstalled, unmodified parts in their original, undamaged packaging. There's no restocking fee on returns in that condition. Installed, modified or shipped special-order parts can't be returned. Neither can electronic tuning devices or ECUs once they've been registered, flashed or connected to a vehicle. Please email us to request a return before sending anything back. See Shipping & Returns and our full Refund Policy.

My order arrived damaged, wrong or incomplete. What should I do?

Email us within 30 days of delivery. Reporting within 48 hours helps us speed up carrier claims. Include your order number and photos of the item, the packaging and the shipping label, and keep all packaging. Don't install a damaged or incorrect part. We'll replace it or refund you in full, including shipping. Return shipping is on us.

How does apparel sizing work?

KSeries apparel is printed on demand, and sizing details are listed on each apparel product page. If you don't see the measurements you need, email us before ordering. Each item is made for your order, so we can't accept returns for wrong size or change of mind. Misprinted, defective or damaged apparel is replaced or refunded.

What payment methods do you accept?

We accept major credit and debit cards, plus the payment options shown at checkout. Every payment is processed securely at checkout.

Are these parts street legal?

Some performance parts are sold for competition or off-road use only and may not be legal on public roads where you live. Check your local emissions, inspection and road-use rules before you buy and install.
