CNC Machined billet T6061 aluminum double O ringed 102mm throttle body spacer.

1/4" thick to minimize interference.

The double O ringed spacer eliminates the need to use RTV to seal the throttle body on a 102mm ported LSA supercharger snout (106mm maximum inner diameter).

The single O ringed spacer allows the spacer to be sealed with RTV to the snout and provide an O ringed seal to the throttle body. 
This will work for all 102mm ported LSA supercharger snouts.

Wide temperature range silicone O rings and extended screws are included.

Made in the USA.
