I bought the car with 76K, and I've never missed a shift. But when I opened it up, it had 7 of the 8 intake retainers cracked at different stages of disintegration. Why I did it? Because someone on these forums suggested it as part of preventative maintenance.

Do I regret it? Heck no, since the otherwise the engine would've grenaded.

that's 76K miles where it could've been mis-shifted by the previous owner.

also, it's possible to over-rev the engine going downhill.

Honda RR, Try to get a few shop quotes. Its just good insurance for yourself. I did it in a few hours with the help of a Honda Dealer tech. He brought the tools, I brought the parts and some cash and he taught me how to do some cool stuff with his tools along the way. Worked out pretty good, actually. I am now confident enough to do a valve adjustment, etc.

AP2 retainers, intake side for sure if you drive aggressively at all!
