  • TBI Filter opening

    Is the TBI on a 4.3-2.8 V6 have the same size top as a 350-305 V8 TBI? (Where the air cleaner sits)

    Thinking about it I'm sure they're 5 1/8".

      Correct. There are the same size. Spectre makes those kinds of parts too.

      Mr. Betterthanyou has a guide. http://members.shaw.ca/betterthanyou...cai/tbicai.htm

      I saw a member on planetisuzoo used a K&N Apollo filter housing on his TBI to snorkel setup. I'm going to use one of those for the CAI on my Trooper as I'm not running TBI anymore.

        That thing on E-bay should work fine. But I wonder how strong it is. The one from Spectre is great it is heavy duty cast aluminum. No messing around with flimsy tin parts.

          Only complaints I've ever heard about the fleabay kits are fitment issues but since your modding it anyways I don't see that as a problem. As a matter of fact I was looking at the fullsize kits myself for when I relocate a bunch of stuff so I can have room to mount a true cold air intake.
