Product Description

The Skunk2 Alpha Header for the 06-11 Honda Civic Si w/ k20z3 motor w/ free shipping. This highly affordable and powerful header which takes from the design from the race proven megapower header from skunk2. Built from extensive racing and testing this header gives you everything you could need. New manufacturing techniques from skunk2 allow for a high quality well designed header to be produced affordable so any enthusiast can enjoy. The 4-2-1 Tri-Y design comes to the end at 2.5inches, this gives a wide powerband thats usual in all rpms. Skunk2 made the diameter of the primaries as small as possible to help increase exhaust pulse speed, while also monitoring this so its large enough to allow a high peak horsepower as well. A fine line that takes lots of r&d and testing, all done by the very capable skunk2 group.

02 Extension: The O2 Extension is a highly sought after by many but not offered by many shops. We made sure it was here and easy to select for our customers. This o2 wire extension extends the wire due to the skunk2 design puts the o2 bung just a bit further to reach. You can either try to extend it, splice it or purchase this easy plug and play extension to ensure a easy and clean install.

EXTRAS:
The Hasport rear engine mount is also recommended to help reduce engine rocking which may help prevent the header from hitting the sub-frame.
You can find that here: Hasport Rear Engine Mount 06-11 Civic Si 
WE Suggest 60-72a for most applications.
