Billet Aluminum Intake Manifold Spacer

It functions by expanding the intake manifold volume and optimizing the air-fuel mixture, resulting in more power and potentially better fuel economy. The spacer features a hard-anodized finish and includes an O-ring gasket for a secure seal. For advanced tuning or performance applications, it is equipped with two 1/8th NPT ports, suitable for methanal or nitrous injection, or as a vacuum/boost source. The kit comes with all necessary installation hardware, including four bolts and washers. An important installation note for this Throttle Body Spacer is that it requires the bypass of the throttle body coolant line. The spacer has a thickness of 19mm and a bore size of 67mm. This Torque Solution Throttle Body Spacer is specifically designed for the 2013-2021 Subaru BRZ, Scion FR-S, and Toyota 86 models. It is backed by Torque Solution's Limited Lifetime Warranty.
