Service was great. Unfortunately, I ordered the one for a 96 mustang GT but the system was different. Customer service sent me the right number for my make and sent me a return pickup.

I have to admit this product is amazing, I noticed the differance the minute I put the filter in my 99 Lincoln Navigator , and the gas mileage improved and the power OMG , i just wish i could've brought the intake kit instead of just the filter. But I will be doing a full performance upgrade in march ;-) thanks K&N for making an excellent product

This is for my motorhome with a V 10. Mileage is never good and power was fine. Wanted to try and increase both. Have only been on one trip since changing out filter. So a little early to have a real complete report. K & N a great product and figuired it would not hurt to help motor breath better. Have the whole system on my pickup and love it. Idea of being able to clean and reuse filter is a huge plus. Shipping was spot on for when they said it would arrive.
