Product Description
The kit replaces your vehicle's restrictive factory air filter and air intake housing. K&N intake systems are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable, reusable and easy to install with tools commonly available.

K&N RAWR!
By Nick Carrigan
I purchased the 57-1516 kit for my 2003 Dodge Durango Sport 4WD.After installation and first engine turnover, I heard a pretty loud whine from the side of the new air filter. According to K&N customer service, this is normal. The noise is somewhat loud with the hood up but muffled when the hood is closed. It's not terrible but it could be a little annoying as it does creep into the interior compartment. At higher RPMs the noise is almost gone but very present at lower speeds. If you're very sensitive to these kind of noises (or *require* a quiet interior) then think twice about going with an air-intake upgrade.Installation is fairly easy if you've ever worked on your vehicle. See the instructions for the tools necessary. One tool that was omitted is a 7/16 hex wrench for tightening the stainless intake bracket..Preassembly Tips:1. Assemble the heat-shield brackets but don't completely tighten down left and bottom brackets. The right bracket can locked down. Install the rubber molding by working it into the grooves. The corners will take some extra effort but they can be fitted without any cutting. When finished, I had 2.25" of excess molding.2. On the intake tube, use a hole-saw to drill out a 3/4" hole as instructed. The hole will be rough. I used a dremel to round off the edges but be careful not to go crazy -- just clean the edges for a smooth fit. Do NOT install the grommet at this time.3. Install silicone tube with the 52 hose clamp. Tighten the hose clamp so it will just barely stay on the silicone without falling off. The other 52 clamp needs to go on the larger portion of the silicone tube. It WILL fit. Unscrew the hose clamp completely and it'll fit fine.4. Build the stainless intake-tube bracket. Prior to tightening the nylock nut with the hex wrench, be sure to verify its look against the wire drawing. Squeeze the ends of the stainless bracket inward until it's tight over the intake tube. It should "lock" onto the intake tube. The 48 hose clamp will fit over the stainless bracket in final assembly. You'll need to unscrew the 48 hose clamp completely.Hood-up Assembly Tips:1. Remove old airbox, air filter, air intake tube and air box hose. Save these parts in case you need them later. Disconnect TEMP sensor connector -- if you have one. Remove TEMP sensor by turning 1/8 turn counter-clock. Discard TEMP sensor gasket.2. Remove the factory bolts (two 10mm and one 13mm) which will be used to secure the heat-shield and stainless bracket.3. Fit the supplied grommet around the temp sensor. The sensor has a thin groove where the grommet fits over. Fit the sensor into the intake tube. Be sure to line up the sensor connector (top should be toward the throttle body.) It will take a little effort to fit the combo into the tube. I could fit about 50% and the other 50% had to be pushed down with a flat-head screwdriver. Be patient and don't damage the grommet. The grommet and sensor should be flush with the tube.4. As instructed, cut the rubber air box vent hose. I recommend fitting the vent hose onto the intake tube before final assembly. Try to line up the hose in its final position. It will take some twisting to get the hose onto the nozzle.Final Assembly Tips:1. Install the heat-shield and tighten necessary bolts. You'll have to relocate the nearby factory connector for the right bracket.2. Install intake tube over throttle body and tighten clamp. Be sure the silicone tube is snug over the throttle body.3. Install the stainless bracket and secure the A/C factory bolt.4. Install the intake tube. Position the stainless clamp as necessary.5. Install the rubber vent hose to the factory return nozzle. Twist vent hose onto nozzle.6. Install and tighten the 48 clamp over the stainless bracket.7. Install the K&N air filter with K&N logo right-side up. Tighten the 60 clamp to secure the filter.8. Re-connect TEMP sensor connector.9. Tighten all hose clamps again -- especially the throttle body clamp.10. Install stickers and carb certification sticker.11. Check for any loose brackets, bolts, etc.12. Start engine and listen for any unusual sounds or vibrations. A mid-range whine from the new air filter is normal.13. Take a test drive and accelerate to at least 4000 rpm. You will hear a throaty RAWR!

A little noisy, If you don't have loud tail pipes. Fits great, You keep your foot out of it will save you gas too.Just all I need now is a Ram Air Hood to direct air flow into it.

There is a noticeable power gain for my 03 Dakota v8. All low end power gains. I've only seen about a 1 more mile per gallon but to me that matters. It was super easy to install and only took about 2 hours.
