Skunk2 Alpha Series K-Swap Header - EG/EK Civic & DC Integra (K20/K24)

Back in stock after a long wait. If you've been holding out for the Skunk2 Alpha K-swap header, this is it. It brings Skunk2's race header design down to a price normal people can pay, and on a K-swapped EG, EK, or DC it clears out the biggest restriction left on the engine. Equal-length stepped primaries, a 4-2-1 Tri-Y layout, and a 2.5-inch collector, all in T-304 stainless.

It Fits Without Cutting Your Cross-Member

This is the reason to buy this header over the alternatives, and anyone who's fought a K-swap header install already knows why it matters. Plenty of competitors' headers require you to cut or modify the front cross-member to clear. Skunk2's doesn't. It's engineered to fit as-is, and it's compatible with most swaps running Hasport engine mounts or comparable kits, on both K20 and K24 setups. That's one less irreversible modification to your chassis and one less afternoon lost to fabrication.

Why Smaller Primaries Make More Usable Power

Here's what separates an engineered header from a big pipe. It's tempting to think bigger tubes always flow better, but exhaust doesn't work that way. Oversize the primaries and gas speed drops, and when velocity falls off you lose the scavenging that pulls spent gas out of the cylinder. You end up with a header that posts a slightly bigger peak number and feels worse everywhere you actually drive.

Skunk2 went the other direction, using the smallest primary tubes that still achieve optimum overall and peak power. That keeps exhaust gas speed high through the whole header, which you feel as stronger midrange and noticeably sharper throttle response without giving up the top end. The stepped primaries let the tubing grow as gas expands, and the equal-length sequential pairing means each cylinder's pulses reach the collector properly timed instead of fighting each other.

Built From The MegaPower Playbook

None of this is guesswork. The Alpha Series is patterned after Skunk2's MegaPower headers, the ones competitive race teams have run for years, and the design came out of more than a decade of racing combined with computerized modeling and a lot of dyno time. Skunk2 has been building custom headers for their own drag, road race, and endurance cars for years. This is that same thinking in a production part.
