Millard, Bend, Oregon
This air filter allows my 3.9 V-6 to breathe. I now enjoy the original torque this engine once had, plus the take off is pretty sweet. It hasn't done what I would have liked...increase gas mileage, but it runs smoother and sweeter.

I've had this filter on my 1991 Dodge Dakota 5.2 liter 4x4 since new. Originally purchased at Ramchargers ....blast from the past...lol....filter was still in excellent condition but the rubber was starting to deteriorate. ...called customer service. ...unbelievable. ...no problem sir we're sending you a new one expect it in 4 business days... wow...I'm speechless. ...all these years nothing but K&N filters air and oil on all of my cars and toys and I've had a few....first time I've ever had a issue and they've made my years of loyalty all worth it in a 10 minute phone call on a Saturday afternoon. ...thank you so much Jerry Falkner Mopar parts Division world headquarters Centerlinem MI
