This section will be dedicated to fittings that I have designed for the B58 Gen1 & Gen2 (TU) Intake Manifold. The Cap Fittings will be ideal for people that want or have deleted their EVAP and want to clean up the look of the manifold with useing billet alumnium fittings vs silicone/rubber caps or plastic caps.
 
You will notice that some fittings are listed to be compatible with both stock/OEM Intake Manifolds as well as Aftermarket Intake Manifolds while others are listed as one or the other. This is due to the irregularities in aftermarket manifolds as well as the fact that because the aftermarket manifolds are metal, they have left give than the OEM plastic. Fitment has only been confirmed for what is listed so do not try to fit a Stock/OEM designated fitting on an aftermarket Intake Manifold.
 
With the Intake Manifold Cap for the Front of the Intake Manifold, regardless if you select Aftermarket or OEM Manifold, it will be supplied with 2 pairs of O-Rings (4 Total) of 2 different sizes. the OEM Intake Manifold will always use the smaller of the two, while aftermarket intake manifolds may use the bigger size. Just play around with the O-Rings and see which ones work best with your aftermarket Intake Manifold. It will also be supplied with the Allen head screw as well as the Allen key.
 
for theIntake Manifold AN10 Adapter fitting, this will automatically include an AN10 cap with a 1/8NPT tap (that will be capped for you as well). This can be used for boost reference, etc. This is also the same for the Intake Manifold Cap w/ 1/8NPT. The cap version will be for people who want to Cap off that front port in cases where they have deleted their EVAP but still may want to use that port as. a boost reference, etc.
