I started the install today and had to re-read all 14 pages here. First mistake I made, is not realize that there is o-ring. No wor.ies, got to get some silicone or gasket maker. 2nd mistake is that I have not purchased the 3" intake tube and silicone elbows.
Size matters! Though I haven't had a chance to test due to other mods, there is no doubt I'm going to pull at the least 20hp making it the best bang for your buck item.
That's 996 TB vs 986 TB
