Re: K&N Air Filter vs. TRD CAI ???
K & N Filters have always been very power full.
I was used several times on rally cars, including the air box Webber carburetors.
However, and I could be wrong but I think everything depands use that one wants to do.
If it is to make a lot of asphalt no problem with the K & N for the one against which many of the TRD off road will be more advisable as well protected, it will suffer less from dust, mud and water.
Besides, I was ready to buy a TRD filter but reading this post I think I'll have a K & N because I made almost no off road, I prefer to gain power
