Any one using a K&N air filter in place of the stock factory one on an RX300? Also do you notice any difference in performance or fuel efficiency with it?

 

Not too much power gain but milage has increased by about 5-8%. Do a search, there were many previous disccussion on this.

 

Right now, I have not noticed a gain in MPG, but have noticed an increase in the HP. Most of the time I am driving at an 8,000 foot elevation though, but at sea level, I have noticed the MPG increase about 3-4 MPG

 

Thanks for the tip and info.

Looks like most people have reported a slight but noticable increase in MPG.

 

A few month ago got a new K&N Air filter for my Jeep GC as a replacement to my stock one. I did not notice any improvements like gas mileage, or increase engine performance. So, I can feel no improvement whatsoever. Not worth the money as I can feel. I do not think that was a good investment. Unfortunately ...
