J'S RACING Stainless hearder 4-1 with thermal wrap (GD1)
This is our very popular stainless (SUS304) header combined with a special thermal wrap. The thermal wrap is also used for our Tsukuba Time Attack Special Race Car.
The thermal wrap increases the exhaust temperatures and velocity, which contributes to higher horsepower and lower engine bay temperature. One of the weak points for the Fit is a rapid temperature rise in the engine bay when the car is driven hard. The thermal warp works very well to prevent the problem.
The 4 (28Ǿ)-1 (40Ǿ) structure increases both torque and power significantly 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.
It works great for L13A to maximize the engine potential.
This special header for Fit performs very well at any driving stage.
● A new gasket is included.
● A fitting hole for A/F sensor is added.
● Application: Early model to the current model 1.3 liter Fit, both FF and 4WD
※ After the several years, the welded area might crack from the vibration caused by the deteriorated engine mounts. Please consult your local shop for the repair.
