LQ9 "LS" Coil Mounting Kit for RB26 - Out of Stock

RB26 to LS Coil Conversion Instructions -

This kit along with the Wiring Specialties harness (not included) fits neatly under the factory RB26 coil cover with no rubbing or touching. You will also use completely unmodified D585 coils; no cutting the grounding straps, ears, or case. This allows easy track-side coil replacement. The harness fits the coils easily and is removable with no hassle. It also does not interfere with the VCAM cam sensor if equipped. You will reuse your stock RB boots and stock RB springs.

LQ9 coils are durable, powerful, inexpensive, and readily available. Everything your stock coils are not! This conversion also eliminates the stock igniter box which is a common fail point.

Just a bit of data for the people wondering why this conversion is needed: on stock coils we were having plug blowout issues around 17-18psi and misfires at lower revs at WOT. With these coils the misfires are gone and we are at 21psi without a hitch. 

Note: Many of my customers have installed this kit to their RB20s and RB25s and have reported great fitment. However, I have not personally fitted this to any motor but the RB26 and cannot guarantee fitment on another motor.
