Just installed an ITR Intake Manifold, AN-R Intake Manifold Gasket, Put Honda MTF in my tranny, and drove around on my new Neuspeed Springs. Here goes my review... ITR Manifold- It feels like I lost a small amount of low end power but up top from 6k-8k feels slightly stronger. Nothing major, just noticeable. I'm still using my stock B16 Throttle Body so maybe it's being restricted a little. With the amount of work and time it takes, I say the ITR Manifold isn't worth it unless you decide to go FI or run some aggressive cams with a ported head. I'm running ITR cams BTW. AN-R Intake Manifold Gasket- The good...This gasket does exactly what it is intended to do and that is keep the Manifold from getting heat soaked. I let the car idle for 10 minutes, drove it for 10 minutes, let the car idle for a couple more minutes, then I went and touched the manifold and it felt like the car had only been on for several minutes. I could hold the manifold with no problem at all. I could never do that with the OEM Gasket. Now on to the bad... First, the material the gasket is made out of looks like plastic they make Hot Wheels with. The quality seems kinda poor but like I said earlier, it's doing it's job thus far. It didn't line up properly on the head it was off maybe 1/16th of an inch but since it's not too flexible, it felt like I had to force it on, not to mention some of the holes were sligtly too small to fit over the mounting studs. In the end, I suggest going with Hondata. The AN-R Gasket is only $35 and that is exactly what you get, a cheap $35 part Honda MTF- I threw some new axles on my car and decided to go with Honda MTF this time around. Honda MTF is the shizznit. I had Synchromesh in it and i'm 10 times happier with the Honda stuff. This stuff made my 3rd gear grind almost non-existent and it's easier to get into reverse now. Using this stuff in my tranny is definately worth it to me. The synchromesh did work better than regular 10w-30 motor oil but the Honda MTF turned out to be the best so far. Neuspeed Springs- At first the car didn't look low enough for me but now it doesn't look too bad and most importantly, they ride great I was running EBay Coilovers before and I must say these springs are a million times more comfortable and let the car handle way better. I'd suggest these springs to anybody with an EF. Well there you have it guys. Once again, this is MY Review. I can give 2 drops of monkey piss what kind of experience your cousin's-uncle's-aunt's-sister's-father in law's hamster had. I am speaking about what I experienced.
