FAQ

What makes K&N air filters different from regular filters?

Our race-proven filters use layered red oiled cotton gauze for superior airflow while trapping dirt. They’re washable and reusable, delivering +50% more airflow than paper filters – just what your engine needs for peak performance.

How do I know which filter fits my vehicle?

Use our “Cars and Trucks” or “Powersports” menu categories to search by make/model/year. Universal filters work with custom setups – measure your existing filter or intake system for compatibility.

Do cold air intakes really add horsepower?

Absolutely! Our dyno-tested intakes can deliver +15HP by reducing air restriction. Like all K&N products, they’re engineered for measurable performance gains.

How fast will my order arrive?

We offer two speeds:
FAST TRACK: 10-15 business days via DHL/FedEx ($12.95 flat rate)
ECONOMY RUN: 15-25 business days via EMS (free on orders over $50)
All orders process within 1-2 business days before shipping.

Do you ship worldwide?

Yes! We deliver to most countries except some Asian regions and remote locations. International customers may need to pay import duties – these aren’t included in your order total.

How can I track my package?

You’ll receive tracking info via email when your order ships. Use the carrier’s website (DHL, FedEx, or EMS) for real-time updates from our Raleigh facility to your garage.

What’s your return policy?

We offer a 15-day satisfaction guarantee. Return unused products in original packaging for a full refund (minus shipping). Contact us at [email protected] to initiate returns.

How long do K&N filters last?

With proper care, our washable filters can last up to 50,000 miles before needing replacement. That’s 5-10 times longer than disposable filters!

What payment methods do you accept?

We accept Visa, MasterCard, JCB, and PayPal for fast, secure checkout. All transactions are encrypted for your protection.

Why was my credit card declined?

Common reasons include: insufficient funds, incorrect CVV code, or your bank flagging international transactions. Contact your card issuer if problems persist.
