BMW N54/N55/S55 Phenolic Intake Manifold Spacer
Now available in black. It blends into the engine bay for a cleaner look, the 1/4" spacer offers superior thermal insulation between the cylinder head and the intake plenum. This can be useful when plumbing custom intercooler piping or rotating the intake manifold. This is a Must have for anyone running an Aluminum Aftermarket intake manifold. Which Heats up the engine bay and intake temps quite fast. Withstands up to 500°F
Why it works: The concept behind the phenolic spacer is simple: isolate the heat produced by engine from the entire intake tract. This results in a cooler path for the intake air. This leads to lower and more stable intake air temperatures (IATs). Lower IATs mean you have the capability to make more power with your current set-up.
Twisted Tuning's phenolic spacers are engineered and manufactured by us. The spacer was designed using the OEM Head and Intake plenum to ensure perfect fitment.
To help with sealing on the engine side of the spacer we recommend the following be applied to the engine side of the spacer:
Each spacer is then CNC machined from a single piece of phenolic.
