Celica Forums General Discussion Engine and Performance K&N CAI

I hear a lot about the AEM and Injen CAI's, but how is the K&N CAI in comparison? Does it bog like the AEM and Injen? Does it produce more or less power? Also, does anyone know if a CAI will void your warranty?

i had teh short ram and was happy with it.

K&N Filter I've head good things about...never heard of anyone having a K&N intake in their Celi though Injen or AEM are both good brands. I've had an Injen short ram for over a year and it's awesome You'd have to check the K&N site for more info. ANY intake or performance part can void your warranty if the service dept. thinks it might have been a factor...or if they're in a bad mood.

I have a K&N Short Intake and I'm happy with it allthough I can't compare it with other brands. I didn't buy the filter for more power. In fact I didn't even buy it because K&N needed a demo-car over here in Europe.
I don't really believe that the measurable increase of horsepower is also noticable when driving. It's all in the head because of the sound. But I do like the sound and the looks.

The K&N CAI looks like an exact copy of AEM. Maybe AEM sold its Gen 1 design to them, since they're not selling it anymore. Their short ram looks like Injen, as well...
