steviej Posted June 8, 2003 Share Posted June 8, 2003 I have an '02 ES (1MZ-FE). The stock Denso filter and the K&N match on performance (ie acceleration, etc). Simply stated you won't get any performance enchancements from switching to the K&N filter in the oem stock air box. I cannot speak to changing to a different air delivery system such as a short pipe, cold pipe, ram, etc. MPG The big difference I found with switching to the K&N, I picked up 3 mpg on city/round town driving and close to 5 mpg on all out highway driving. $$$ savings on filter replacement I never have to buy another filter again. At approximately $12-30 depending on where you buy and how often you change....it will add up. try it, if you don't like it, switch back. The cost of a K&N by mail order was less than $40. The recharger kit is less than $10 and will last the life of the car. steviej Quote Link to comment Share on other sites More sharing options...
m2pc Posted June 29, 2003 Share Posted June 29, 2003 I just bought an Amsoil Drp in filter. Cheaper than the k&n and re-usable. I'll let you guys know if there is any increase in MPG. I doubt any performance increase. Quote Link to comment Share on other sites More sharing options...
m2pc Posted July 15, 2003 Share Posted July 15, 2003 Well, been driving with the Amsoil free flow and notice no increase or decrease n MPG. This can be due to 1. Oil needs to be changed soon as opposed to prior numbers taken after a fresh oil change. 2. Summer time - I'm using the AC (this will bring down the MPG's) where the prior numbers I didn't crank it on. Quote Link to comment Share on other sites More sharing options...
gav_logan Posted July 15, 2003 Share Posted July 15, 2003 Is there much work in changing the air filter? Quote Link to comment Share on other sites More sharing options...
NeiLtYmE Posted July 15, 2003 Share Posted July 15, 2003 no , depending on the model... just snapping open the box and dropping it in.... Quote Link to comment Share on other sites More sharing options...
