Please DO NOT Post In The General Section

From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.


The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.


For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

Again if you have any questions, PM me or one of the other mods.

    H23 IM vs. H22 IM

    I just wanted to know how you could tell that the intake manifold is from an h23 or an h22. Is there a serial code or something that separates them.

    just search for pics of both. there are obvious visual differences in the two.

      The plenums are the same, as they both are stamped "p13" but the runners are different. H22 runners would be stamped "p13" and the H23 would be stamped "p14". That's the big difference between the 2 IM's.

        Thanks granite, that just helped me out alot! I bought a Intake manifold and it was titled wrong on ebay. i was pretty sure that it was for a h23 but now i am positive.
