Akmee K-series Swap Header
R-crew K-series 4-1 head was the most popular and most copied K-swap header in history... after a long hiatus and not  being available from 2008-2013 --  the ORIGINAL is back!  (under a new owner - Akmee).

Precision handcrafted merge collectors and updated with shortened primary, extra o2 sensor bung, as well as more durable beehive spring hooks. The slip fit is carefully hydraulically reamed to ensure leak free seal. Expertly crafted the premium quality is easily seen.
100% aircraft stainless steel 304 throughout the construction. Header flange port is slightly bigger than the OEM port size for unrestricted path (some of the poorly made headers out there are quite bad due to poor quality control in comparison).

Metric size spec:

  • primary starts at (4) 48 mm step to 51 mm merge to (2) 54 mm merge down to (1) 56 mm choke and finally venturi to 63.5 mm collector.

Standard size spec:

  • primary starts at (4) 1.875" step to 2.0" merge to (2) 2.125" merge down to to (1) 2.200" choke and finally venturi to 2.5" collector.

The Akmee K-swap header is designed to fit 92-00 Civic & 94-01 Integra with K20 or K24 engine swaps using Hasport or similar style engine mounts.
