Depends, I guess, since most other gaskets are "single use." :D

The orange/brown ones require an OEM gasket on either side of it to seal properly; I do not like this design as it is more prone to leaking. The white ones do not require a gasket as they have a slight amount of squish to them (these are what I've used and recommend). I know people will claim otherwise, but I consider these to be single-use only like most other types of gaskets.

I have the white one. It's the one MAP makes for our cars. I have had it since my fp black build. So its been reused several times.

Yep, I am guessing I should've replaced this gasket I will get a new OEM one this week and put it on this weekend. I trust the OEM one to seal properly vs one of those I guess.

Get a new white one, reusing it that many times is your problem. They work well. I had one on my IX and X.

My buddy said those plastic ones can have sealing issues and said the OEM one is the safe bet.

Looks like MAP doesn't even make theirs anymore, at least its not on their site. And they only show the Boomba one which is 85 bucks.

Not sure what the hell all those bolts and that other piece are for pictured here...

Seems safter to go with this:

Is there a reason that it's not a good idea to do OEM?

They're about $20, you just have to ask for one. Bill always knows what people are talking about when I refer them.

People say a lot of things, 99% of which have never actually touched the product...I use/recommend/trust things I've actually had good experiences with.

Your car so it's your call, but it sounds like you've had good luck with it thus-far, if anything, it went beyond expectations since you reused it multiple times! OEM is never a bad idea, it just leaves room for improvement on the table.

No I hear ya.

I just don't want to have to pull the intake mani apart again after I do it this week/weekend.

Especially since my buddy who is a mechanic for infiniti is helping and he recommended OEM. SO if I don't go OEM, he helps and it leaks still, he will kick me in the nuts lol.

I am fighting internally, as I don't want to leave power on the table but I just want it to work.

Simple: See what's in-stock immediately available for wrenching this week :)

One side-note: Sometimes when manifolds get ported they slightly warp due to heat and the flange face isn't as true as it was from the factory; the white gasket allow for more squish than the OEM gasket does. Cobb had this issue with a ported IM (MAP Rev2) and the OEM gasket wouldn't seal it.

Well that was my thoughts as to why the leak is there, because I got a MAP rev3 since last time it was isntalled. So I assumed the white gasket I had was formed to the OEM manifold and after the porting, the surface changed slightly and it wouldn't seal.

If they have the white one in stock I will go for that I suppose. It's not the end of the world to do the IM twice I guess. And if it has more "squish" than OEM, that is probably a good thing.

Map doesn't make theirs anymore. But they sell this which I bought:

Bill said it was basically the same thing. Almost looks like this is what MAP maybe rebranded for theirs. Anyway, gasket and battery ordered (got the odyssey 680 instead of the 925 this time as its cheaper and lighter). My battery actually tested good at my buddies dealership but just didn't seem to want to start the car so not sure what gives. The car started fine when i left the charger on there though.

If this battery doesn't last I am going to put a normal one back in there or start checking my grounds as something has to be up with it.

I had good luck with the STM battery kit I put in my car. Pretty nice for $150 shipped (battery, bracket, hardware, etc.).
