M42 / M44 Phenolic Spacer Kit - Reduce Intake Temps!
 

I have put together some phenolic spacer kits for M42's and M44's which isolate the intake manifold from the cylinder head. I developed and installed this product on my Supercharged M44 as the intake manifold and blower were getting really heat soaked from all of the extra compression and power and thus heat coming off the motor. It reduced my intake air temps almost 20 degrees F and the actual manifold surface temp over 40 degrees!

This is perfect for boosted applications and I have not tested it on an NA set up yet, but should also help keep NA intake manifold temps down a few degrees as well. We all know that the NA 4 bangers need all the help they can get.

The Spacer is Water Jet cut out of high grade phenolic fiber board which is rated at nearly 600 degrees! It is 10mm thick and for $135 the kit comes with extended studs, 2 additional locator dowels, phenolic washers, and 2 new manifold gaskets. Includes standard USPS shipping.

Let me know if you have any questions.

Nice! Is there anyone out there with a DASC and a spacer installed who can comment on bracket alignment/mods needed for your install? How thick was your spacer?

Thanks! :)

Check the r3vlimited and e30tech posts for user feedback. I have sold about 20 of these over the last 3+ years and nobody has ever reported a problem with fitment.
The spacer is 10mm and when I installed mine, I simply added some washers to the bracket to space it out a bit.

I like the concept. PM me your payment info. I'm in. :cool:

Anyone in for another run of these? Trying to get another group together

I’d buy one
