Fitment tips
Fitment can come down to more than year, make and model. Sometimes the sub-model decides, so start with the fitment table below.
- Drive type. If your car is all-wheel drive, make sure the part is for all-wheel drive, not rear-wheel drive.
- Engine size. For engine parts, make sure the engine size on the product matches your engine.
- Transmission. Manual and automatic cars often take different parts.
- Body style. Sedan or hatch, two-door or four-door, cab and bed length on trucks.
Manufacturer data can sometimes have imperfections. Still not sure? We are happy to help.

Despite its unorthodox appearance and seemingly haphazard design forced to fit in limited available space, the OEM intake system is incredibly efficient. Wholesale improvement upon the design given the packaging limitations meant that a full re-design was not going to be feasible at a price point that would be accepted so a simpler more direct approach was taken. Improve air flow in the factory system where it was restricted - the filters themselves. Simply going from the stock paper filters to the Dinan multi-layered cotton filters not only increased flow by nearly 20% but also resulted in some modest power gains in the mid and upper RPM range. While happy with the results, the engine bay remained lack luster and devoid of any visual hallmarks.
Installation Instructions- Massive detail rich, gloss UV coated, 2x2 carbon fiber engine cover for maximum under hood appeal.
- Set of drop-in multi-layered cotton high flow filters for increased flow and superior filtration.
- One word: Magnets. The mounting hardware solution for those that wish to be free of clutter.
- More Flow: 18.6% greater than stock (Stock: 862 CFM, Dinan: 1022 CFM @ 28" H2O per bank).
- More Power: Max gains of 7 WHP and 8 lb-ft of torque @ 4750 RPM.
- 50 State Emissions Legal: CARB EO D-176-54.
- Quick and easy installation.
