Maximum Flow Pro5R Filter

This intake kit replaces your restrictive factory air box. It features a 3-angle aluminum velocity stack adapter, 1.6mm powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter.

This version uses aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.

By removing your stock intake air box, you are removing the most restrictive portion of your intake system, increasing both horse power and torque, improving acceleration as well as throttle response.

For the maximum benefit in performance, we recommend upgrading your engine software with the Shark Injector (Click here for more info on the Shark Injector performance software.)

Want an extra layer of defense? Add a pre-filter to prevent water, mud and sand from congesting your air intake system. This simple upgrade slides over the aFe filter of this intake kit, much like a sock, giving you an extra layer of defense, and extending the cleaning interval of your aFe intake's filter element. Best of all, using the Pre-Filter does not significantly diminish your air filters performance the smooth rush of oxygen keeps rolling right into your engine. To add the pre-filter, just select the option for the drop-down option below.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Engineered to perform, Powerflex performance polyurethane differential bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.
