K&N 33-2233 Air Filter Product Reviews

Thursday, March 29, 2018 - Part 33-2233
This is at least the 3rd air filter I have purchased from K&N most recently I purchased it for our Jeep Grand Cherokee in order to attempt to get better gas mileage. I know vehicle and driving habits contribute to K&N performance. Since I put this in which I replaced a nearly new generic air filter. Our vehicle has an average reading of 1 to 1.5 miles per gallon better fuel economy. I still intend to do a tune up and engine/fuel system cleaning since the vehicle is approaching 90k miles. I noticed a slight power increase in 2 of my other vehicles. I am very happy with K&N products. Well worth the month in my opinion. Mechanics always compliment how well my cars are maintained and I contribute K&N to my care and maintenance.

I have always used these filters, and I find them great. At present I have one in a Jeep Liberty 2.8 CRD 2007. I will always continue to use these products, as they're well made and have a long history. I also use K&N oil filters.
