once again

CXJ PERFORMANCE has brought the phenolic thermal intake spacers for the 7th gen maxima and altimas. these spacers are made from 3/8 thick high grade phenolic. The spacers will isolate the throttle body from the manifold and also the manifold from the block.

with the isolated areas spaced off this way the manifold will run about 40 degrees cooler thus creating colder , denser , heavier air into the chamber resulting in more horse power and greater torque.

feel free to post any question

What is the lead time for the build?

 

it shouldnt take more than 2 hours

 

I find this hard to believe since this is a plastic manifold to begin with, not metal like the older 3.5 intake manifolds.

 

this. the composite plastic of the newer manifolds is not as susceptible to heat-soak as previous generations.

also, have these been port matched or simply cut as essentially thicker gaskets? finally, are there any dyno tests proving the gain of these spacers with the composite manifolds?

 

sorry i know this was a crude way of releasing them.

i released two 7th gen products and one 5th and 6th gen products on the same day

the second picture shows that they are port matched and not just an raised gasket design. the 7th gen has rubber gaskets built into the manifold. testing is showing very good gains and will be posted shortly as were with my 7th gen bop plates numbers. heat soak will not be as great with the older manifold compared to the 7th gen plastic manifold but there has been a reduced amount of heat removed from the manifold. with the additional height from the spacers and reduced heat these in fact have produce more power across the band.

 

we'll know real quick what the temp changes are, using an OBD-II tool to pull IAT data from the ECU and looking into some before/after dyno runs.

currently im seeing 90 degrees fahrenheit with my CAI while moving, about 110-120 when idling. with the SRI i was seeing 120 while moving, 170 while idling. i think its safe to say we're not expecting 50 degrees while moving which would be ridiculous, but I can def see how it could pull those idle temps way down depending on how hot you're running

 

personally, I don't see how putting a heatsink on a plastic intake could help heat soak. I think any gains would come from the increase in intake runner length which you have created by adding the spacer. It would be very interesting to see some real data on temp changes.

 

I did pretty thorough testing with my CAI I'm gonna do the same with these and post it up when I have some actual numbers. I'm very curious myself to see what these do, should have some info very soon
