Phenolic spacer
So I'm thinking of doing a phenolic spacer on my Weistec stage two blower. i have been finding that the IAT's could use some more efficiency and this may be a a good way to get the ecu to not pull timing. I do know this has been done with minimal results in the past with the m113k platform but that setup is different. Any constructive thoughts?

I have a set of Thermalnator phenolic gaskets sitting here with new OE gaskets (2 sets) and intake manifold bolts. Meant to do it yesterday but got busy with other things. If you do a search here, there have been a few who tried it but no data to show any difference. The concept/theory is sound enough, and other cars really benefit from the intake being isolated from the heads with these, that I tought it was worth a shot.
One thing I was alerted to, is that these gaskets effectively make the intake manifold runner length longer (3/8"?). Not sure what impact that has, if any. I don't think its a major concern.

It's the whole reversion and then ram effect of when air bounces against the valves when they're shut and then time it takes for it to bounce back against the plenum and then finally back into the engine when the valves open again. When the runner length and rpm range/vacuum is just right, an extra amount of air will get shoehorned/rammed into the cylinder. It's a bit like boost....only it gives a few hp and not a hundred

It's not in the same platform or engine level, but I installed one a few months ago in my 2010 Nissan Xterra (4.0L V6), and the results that people reported on forums and from the manufacturer, well, I didn't feel a difference really.
If you asked me today if I would install it again the answer would be no.

I have been using the spacers from SIKKY for just over a week. Since then I no longer have the hot start, light engine shaking I used to have. Kind of like the fuel is cooking in the rail. It wasnt the manifold or gaskets because I had already swapped the intake a few months prior and had the same hot start shaking before and after. I also noticed that the car feels like it pulls stronger then before from 65+. Sorry no before and after dyno runs. I also made a pigtail harness for the IAT and remote installed it into the right air duct in front of the engine oil cooler. So far no weired running issues or CEL I lugged it a few times up hill. Had a light ping one time no other issues. This is with a NA setup not with a SC.

I've been using them on boosted motors for years. They make a big difference in the intake temps. I looked for some data to show before and after for IAT but no luck so far. You couldn't stick your hand on the intake manifold before now it's nice and cool. Well, not cool but you can definitely feel a big difference.
