Ships from Dinan — this item ships direct from the manufacturer. It usually goes out quickly, but because it leaves their warehouse rather than ours, delivery can take a little longer than our in-stock parts.

While factory paper filters function admirably, they can be restrictive to performance goals given the material used. They also require being replaced numerous times during the lifespan of the vehicle, which can add up to a substantial amount in maintenance costs. Limited performance and increased maintenance costs are never ideal but can be resolved effectively and economically in the case of filters. Dinan High Flow Drop-in Replacement Filters are constructed of 4 layers of cotton gauze that allow better flow and less pressure drop than the stock media. This equates to the engine not needing to work as hard to make the same, or more power. Additionally, the use of oiled cotton media means that the Dinan filters are washable/re-usable while still retaining excellent filtration and ensuring your engine runs clean for the duration.

Dinan High Flow Drop-in Replacement Filters are a direct upgrade to your factory intake system and will instantly provide better flow to assist your engine in achieving maximum performance and efficiency!

When upgrading to a complete Dinan intake system for best performance, is not available, possible, or within the budget, Dinan High Flow Drop-in Replacement Filters have you covered!

Manufacturer's Warranty — Dinan

Dinan warrants its Performance Products to be free from defects in materials and workmanship, and the term depends on the car. If the vehicle is still covered by the original manufacturer's new car limited warranty (4 years or 50,000 miles — 80,000 km in Canada — from first retail sale; US and Canadian specification vehicles only), the Dinan part is covered for the remaining term of that new car warranty, and an Authorized Dinan Dealer repairs or replaces the defective Dinan component without charge for parts or labor, including any original manufacturer component directly affected by it. If the car is out of its new car warranty, Dinan Performance Products carry a 2-year, unlimited mileage warranty from the date of original purchase; labor is reimbursed at the dealer's standard flat-rate, but repairs to affected original manufacturer components are not reimbursed. DINANTRONICS Sport, DINANTRONICS X and DINANFLASH handheld units are 1 year, unlimited mileage; refurbished products are 90 days; and racing-only parts are guaranteed against defects in workmanship only — they are not warranted against wear or failure and may affect the BMW factory and emissions warranty. Dinan's warranty is transferable when the vehicle it was installed on is sold. A lawful invoice as proof of purchase is required, and the defective part must be returned to Dinan for verification before any adjustment. Not covered: return shipping, towing and rental car charges; unauthorized modification of a Dinan part, or damage from using other manufacturers' products alongside Dinan systems; non-DCT clutch assemblies, brake rotor warp and friction materials; maintenance items such as spark plugs, filters, lubricants, fluids, coolant, drive belts and light bulbs; negligence, abuse or improper installation; engine damage from altering Dinan's original boost pressure; improper or contaminated fuel; collision damage; environmental damage, flood, fire or road-salt corrosion; and any vehicle operated in a competitive event or subjected to aggressive track conditions. The warranty is void if the VIN or odometer has been altered, if the vehicle was declared a total loss or salvage, or if it has been used in competition. Note that installing performance products may affect the vehicle manufacturer's own new car warranty. Because Dinan handles claims through an Authorized Dinan Dealer, if you bought it here, contact PitStopTuning and we'll file the claim with Dinan for you rather than approaching Dinan directly.

Warranty terms are set by the manufacturer and may change. Contact us if you need help with a warranty claim.
