Home / Subaru Tuning / Subaru Gaskets Seals Nuts & Bolts Product Description Subaru Impreza V5 + Thermal Inlet Manifold Spacers And Bolt Kit For The Version V5 1998 onwards including Spec C 10mm Thick. 8 Longer Cap Head Bolts. A pair of insulating inlet manifold spacers designed to keep inlet temperatures down.These will help prevent heat from conducting into the alloy inlet manifold from the cylinder head. In theory, because of the cooler & denser inlet , an immediate power increase should be evident, but their main strength will be in helping to keep temperatures under control after prolonged engine use. Drag race or pit-lane situations where a stationary warm-up period is unavoidable will always result in high manifold temperatures (so making immediate power levels suffer), while hot starting after a period of engine shut-down will also be helped. These high performance composite spacers (approx 10mm thick) are available for all Subaru EJ engine types and are supplied exactly as the original gasket including the holes for the location pins on the cylinder heads. The kit contains 2 manifold spacers and 8 longer carbon steel 8mm cap head bolts. Please Note 4 Gaskets Will Also Be Required To Fit These Spacers. Suitable for:- V5 onwards including Spec C with one piece inlet manifolds. Engines with tumbler blocks will require longer bolts please see below http://www.advancedautomotives.com/thermal-spacer-bolt-kit-v7-sen758-4860-p.asp Specifications Brand ADV Customer reviews No reviews left yet Write A Review Most RecentTop Rated Description Subaru Impreza V5 + Thermal Inlet Manifold Spacers And Bolt Kit For The Version V5 1998 onwards including Spec C 10mm Thick. 8 Longer Cap Head Bolts.
