Product Overview

Are your factory coil pack not quite enough for your boosted or high-performance motor build? These coil adaptors are for you!

Our coil adaptors are made from high quality CNC anodized aluminum and they allow you to use the Honda K-series ignition coils on your phase 2 SOHC Subaru heads, specifically for 1999+ non-AVLS heads.

The Honda K-series coils are proven to work with over 400whp on high boost applications and there are upgrade paths available beyond that.   

The Honda K-series coils are readily available at all auto parts retailers including Japan-made DENSO coils (673-2301) from companies like RockAuto for $39 each. The coils can be operated in full sequential ignition or in OEM style wasted spark configuration.

NOTES: 

  • The installation of the coil adaptors require the drilling and tapping of your valve cover. It is recommended that this modification be done by a competent machinist. We include instructions
  • Wiring is not included. Complete wiring diagrams will be included but the wiring design will be dependant on the type of ECU you arere using
  • These have been thoroughly tested using a standalone engine management system (Link G4+/VIPEC) and it is highly recommended that your engine management system be capable of adjusting dwell timing for your coils. Use dwell tables to aid setup of your system.

    2006 EJ253 avls turbo build, stock ecu

    Posted by Preston Radde on 30th Apr 2020

    Just got my adapters in the mail. Turns out I have a different set of honda coils instead of the reccomended (my 099700-116 vs rec 673-2301) i'll need to make a slight modification for that but then again these are made for non-avls. Shipping was very quick considering, quality is VERY good and the black anodizing is perfect. I bought the set with the piggytails and those pictures don't do the length of the wires justice they are just shy of 18 inches which is gonna be enough to wire to the harness no problem and come in two colored signal pairs to pair up cylinders 1-2 and 3-4 super clearly. Overall amazing product, shipping and customer support so far!
