Genuine Hks 4age 20v Racing Headers **rare** on 2040-parts.com

Pursue the ultimate exhaust efficiency, racing header.

Exhaust manifold that has been researched and developed with the aim of high dimension by for HKS taking advantage of the know-how of the exhaust technology to pull out the engine performance 100% over the years.  Using the technique a wide range, we have a unique approach to each type of vehicle in order to clear the hurdle that the power-up in the performance security and high rotation in the mid-range.

■ 4-2-1 and devised by the junction of the structure Speaking of the charm of NA engine, still sharp response of high-speed range. However, in the case of street youth, I will be strong demand as much overall balance feeling a sharp response of the high-speed range.  In order to achieve both a sharp response and balanced torque characteristics of high rpm, it is designed to devise a partition plate in the collecting portion the HKS.  To optimize the length from the cylinder block to set part, the adoption of the junction structure (special shape collective part of the 4-2-1), to generate a strong load in the exhaust manifold, low and medium speed that is required I have to allow the torque-up range.

■ Quality that breathes in sophisticated style

Difference of quality, will appear in the form. The texture is high performance that only genuine has alive, will be delivered as a new values ​​of commitment. In addition, HKS does not forget presence of the engine room. The pursuit of beauty using a stainless steel SUS304 having excellent heat resistance and corrosion resistance to the material.  In addition, all of the (association also) was Tig consideration by the beauty of the finish to the welding of the connecting portion from commitment to quality is adopted welding. Tig welding to be carefully carried out by all handmade, beautiful finish we have extended well strength and durability.

■ effect of the bypass pipe to reduce the positive pressure If caused to generate a strong negative pressure, strong positive pressure in the form of naturally rebound will occur. By using coupling the bypass pipe to each cylinder pipe the HKS, Minimize the amount of positive pressure that occurs. Rhythm I have control of "positive pressure", "negative pressure" in the manifold.  In addition, optimized to suit each engine exhaust characteristics the number consolidated position of the bypass pipe. Making it possible to keep a positive pressure without changing the power of negative pressure.Therefore, to eliminate the valley of the torque as shown by the graph, while taking advantage of the maximum (the effect of the seeking to dramatic power-up in the NA engines) inertial exhaust effects, to be obtained easily engine characteristic treat flat it works.
