LSJ Phenolic Intake Spacer

SKU: ZZ-LSJPHNSPC

$99.99 Sale price

Regular price $99.99

A hot engine heats up the air that is flowing through your intake. The engine is aluminum, as is the intake and they conduct heat very well. Your 180 deg engine adds unwanted heat to the LIM which houses the intercooler. That is why you need to upgrade with our ZZP LSJ phenolic spacer. A cooler charge will make more power. Keep in mind that removing heat adds power not only by increasing air density, but also by helping cool your IAT2s down to help prevent detonation. 
  
We isolate the intake from 95+% of its contact to the engine which is what is heating it up. See pic below showing that the heat from the engine is isolated where the intake connects to the engine. 
The engine runs at approx 185 deg and has a direct metal to metal contact with a large surface area on the intake. This is constantly trying to heat the intake/IC system/blower to this temp. This puts additional heat into the IC system and is the reason on summer days you will see IATs at idle/cruise 40 to 60 deg over ambient. While the lower part of the intake has a mounting point, it is very small and bolts to a bracket which then bolts to the engine. This is quite a bit of separation and the contact is small enough to be negligible.

The air under the hood on a summer day is normally around 140 deg but air doesn't do a very good job at heating things, not like metal/metal or fluid/metal. So with the spacer you can expect a much cooler intake, much cooler blower and lower IATs all the time, even under boost. This gives more HP and much more consistent performance by eliminating heat soak and keeping the blower casing to rotor tollerance as small as possible.

All this technology is borrowed from our pioneering work on the 3800's. There used phenolic to shield the blower IC from engine heat with fantastic results.

LSJ phenolic spacer

I was skeptical about the effectiveness of the spacer but on average it lowered my IAT2 about 10 degrees. IAT2 also doesn't get as high when stopped for a long period or when you're running errands and shuttting the car off to go into a store for 15 minutes or so. Great product for the price and a must have for any LSJ.

A must to any build up

The part is very well made and a huge plus to any build. Only had a few small issues while doing the install, but mainly due to my previous modifications made to the engine. Like the silicone radiator kit ( from ZZP) had to be trimmed to fit. So now my supercharger was pushed out about 1cm. So the radiator hose is resting on the supercharger. Not a huge deal though... Also swapped out the bolts for ARP bolts.

Phenolic spacer, worth the money. BUY IT!

You'd think this phenolic spacer would be nerve-racking, going from a metal gasket to 2 paper gaskets and a phenolic spacer...you'd think there might be a leak of some sort, but in reality, this was easy. This mod is best done when you've got the car apart for dual pass/option b install. You won't be disappointed in this product. Well worth the price.
