J'S RACING CL7 Stainless hearder 4-2-1

Header layout  4-2-1

Weight  4.9kg (10.8 pound) Compared with the stock header 10.5kg, our header is 5.6kg lighter

The 4-2-1 structure [ 4(45Ǿ) – 2(50Ǿ) – 1(60 Ǿ)] increases both torque and power for all the rev ranges.

Made by light SUS304 stainless with the thickness of 1.2mm to 1.5mm, the welding, material preparation and assembly are all hand made meticulously by the experienced craftsman.

Compatible with many tuned stages of the K engine from stock, high lift camshaft, high compression, to the bore / stroke up.

This is a special header for CL7 for the special performance.

* We are sorry this header does not fit for the U.S TSX with K24 block.

A long waited J’s Racing special header for CL7.

We have tested it against most of the competitors 4-2-1 type headers.

We are confident you can experience the difference.
