RF Yamamoto GT-Manifold

Description

It is a manifold that has pride to be the most efficient and reliable on the market. The manifold length of each cylinder pipe is equal in length, simply installing these parts is enough for you to feel a considerable difference. Once setting up the computer program’s fuel map it’s possible to increase the engine power by over 30 HP.
To improve the original performance, we at RFY recommend this computers setting, though with a normal computer the performance is still moderate. The normal ratio about 30HP can improve.

O2 sensor extension harness attachment included.
