spacers look real thin? how thick are these spacers and what material is used?

 

The Spacers are a 1/4" thick except for the two lower intake manifold Spacers, which are 1/16" thick. The LIM Spacers are made from a very high quality phenolic which is guaranteed for life. The rest of the Spacers in the Economy Kit are made from an easier to machine insulator which can only be reinstalled and handful of times.

 

Just installed these last night on my brothers 04. Makes a world of difference. Install took me about 3-4 hours but I took my sweet time.

If you need more step by step instructions than the sheets provided, I used the spark plug replacement thread up until the lower intake manifold. After that then its easy as pie with the provided instructions.

Thanks and great product

 

I just snapped some new photos of the Economy Spacers today. They are beautiful!

 

Looks real nice. I had your 5piece kit on my 02. And I'll be ordering for my 04 real soon. Just been debating between the 5pc and the 3pc. You still running free shipping special?

 

Yes, we are still running the free shipping special, but only with our Phenolic Spacers. Please take a look at this thread for more details: http://forums.maxima.org/group-deals...t-lb-gain.html

In all our testing, the 5 piece kit is noticeably better than the 3 piece kit.

With our 5pc kit, you will be insulating the lower intake manifold, which gets very hot, 175-185 degrees. (178 degrees to be exact on our 5pc test vehicle) With the addition of the two thin LIM Spacers, the LIM temps were lowered to 144-145 degrees. That is a 33 degree reduction in LIM temps!

As for the UIM, having the entire 5pc kit installed will lower those UIM surface temperatures by 41-43 degrees. The UIM was 146-147 before. And 104-105 after.

With only the 3pc kit in place, the UIM temps will be decreased from 157 to 127 degrees for a temperature reduction of 30 degrees. And since the LIM Spacers aren't installed, your LIM will still be blistering hot at 175-185 degrees.

When heat soak is taken into consideration during the testing, the 5pc kit really shines as the best. The cooler you keep your intake manifolds, the more power you'll make on those hot summer days when you're hot lapping on the race track or driving in the city from stoplight to stoplight.
