The K&N cold air intake kit is great on my 2005 Ford Explorer. I ordered the kit about 2 years ago. I pull a heavy trailer. The explorer is barely big enough to pull it. Installing this kit is a BIG help in letting the engine breathe. It sounds great and makes me feel better too, putting this load on my car. The installation was straight forward and the instructions were excellent. The installation was no problem. Only 2 minor issues. The airflow sensor mounting pad had a casting lap that deformed the mounting surface. I was able to smooth it out with a sharp knife and light sanding. The other issue was that I mounted the filter such that it was riding hard on the bottom of the intake box. This was my fault. I didn't find out until I took the filter off to clean and re-oil it and found a very small worn spot on the filter. When I install this new filter I will make sure that the filter is free from interference all around. Thanks for a great product I'll be using K&N from here on out.

The 71-1561, 2009-2014 Ram 1500 and 2013-2014 Ram 2500 V8-5.7L HEMI, is a great mod for your RAM with instant results The instructions were good but some points I would like to share. I installed this induction system Friday the 13th of June, 2014. UPDATE: Re-installed on my 2015 RAM Sport Reference the IAT, Inlet Air Temperature, sensor two things to note. (1) Handle with care and confirm no debris on the end of the sensor, my application was blue in color. (2) Orientation of the IAT sensor should be in line with the flow of air inside the tube. Just take note how the IAT is positioned on the OEM intake tube when removing. I applied a very small amount of petroleum jelly on the oring, confirm you seat the IAT fully into the grommet and in the correct orientation. As far as the intake tube fitting many are complaining that they have broken, stating is cheap, etc., contacted K&N, which they have replaced for no charge great customer service BTW But if you follow the instructions it states the following: Plastic NPT (National Pipe Thread?) fittings are easy to cross thread. Install the vent fitting 'hand' tight then turn it two complete turns with a wrench. I used the box end with no problems/issues. The fitting will show approximately 3 threads left and I feel installers observe this and crank it down & snap the fitting. Bottom line of course is to take the time to read the instructions completely, then confirm parts and organize, then start with step 1 and have fun. Make it a slow process and enjoy the moment of your installation of your new mod Then as you stand back admiring your work, treat yourself to your favorite beverage.

Fast delivery. When I've put it I've start immediately the engine and went for a ride, this air filter gave more reactivity into my seat; for it's a very good surprise cause my normal mode is now as the sports mode. So it's working well, I'm just waiting to see if that' gonna save the fuel economy.
