I just installed the 63-9030 into my FJ as well. It looks, and sounds great. I'll still need some more time to evaluate the performance and mileage improvements.
The install was straightforward, and relatively easy except for step #23. The crank case vent fitting just does not fit with the hardware K&N provides. We tried to finesse it, by lubricating the grommet... no go. Then we tried brute strength, the weight of two men. After much effort the vent fitting broke!?!
I’m not exactly sure which of the 3 components is too small vs. large, but when I called K&N and described the problem; they quickly offered to send me out a new grommet. Seems like they may have included a grommet #082000, which is too small for its specific application. I'd urge anyone who has bought this kit to call K&N's 800 number for clarification, and possible replacement parts.
