ZZPerformance is the leader in intercooler research, testing and performance. We are the only 3800 vendor with a supercharger dyno. It measures blower CFM, temperature of ambient air, air out of the blower, and air below the intercooler core. In addition we measure pressure above and below the core, water GPM into the core and temperature of the water going into the core as well as out of the core. By testing over a dozen parameters with various conditions, we are able to bring you performance unparalleled by any other manufacture. While they guess at what 'should' perform, ZZPerformance can guarantee it!

Update 12/17/19: We now include our Gen 2.5 intercooler cores in all of our Stage 2 intercooler kits. The benefits include: Straight through PCV passages, this revision no longer requires swapping the intake manifold to maintain factory PCV function.  The core itself is more efficient, 20% denser core, and the shape is optimized for the actual airflow path.  Internally it is no longer sealed by RTV, it uses o-rings with machined o-ring passages.  It is ¾ of a pound lighter than our old Stage 2 core.  It has ¾” nipples instead of 5/8” for increased water flow.  …And finally, improved machining quality. To read fully about the new cores click here.

Bring your car to the next level of performance with our intercooler. For use with all M90 powered cars. Use 3.0 pulleys or smaller with 0 KR. 300+ HP at the wheels is easily within reach with the addition of our IC. Our latest kit is the easiest to install yet with nearly a dozen improvements over our older kits. Separate system no longer ties into factory overflow, T fill ensures no air and easy priming, new gaskets eliminate PCV issues and extra work trimming.

  • Car idle, streetability and gas mileage remain unchanged
  • Works fine year round
  • Prevents detonation and chipped pistons
  • *Stock PCV function** (no breather required 5-3-06) with our revised intake manifold (must be purchased separately).
  • *Stock EGR function
  • 3/4" lines and fittings
  • New design outperform anything on the market
  • 3 piece core is bolted together and pre-sealed for easier installation

How to order:

Supercharger Generation: The '97-03 Grand Prix GTP, '04-05 Monte Carlo/Impala SS, and '97+ Regal/ Bonneville SSEi/ Park Avenue Ultra/ LSS comes from the factory with a Gen3 supercharger. The only car that comes from the factory with a Gen5 supercharger is the 04+ Grand Prix supercharged. However the Gen5 supercharger can be retrofitted to cars that came with a Gen3 supercharger, if you are going to do that, you will want to select Gen5 instead.

Fuel Rail Solution: The Series II '97-03 Grand Prix GTP, '04-05 Monte Carlo/Impala SS, and '97+ Regal/ Bonneville SSEi/ Park Avenue Ultra/ LSS comes from the factory with a Return Style Fuel System. The only car that comes from the factory with a Returnless Fuel System is the Series III '04+ Grand Prix supercharged.

6 hour install time. The most complete kit on the market with CD based installation instructions including dozens of pictures and step by step instructions.

The new ZZP heat exchangers are custom built for the W-body platform. They are bolt in with no longer require cutting of the factory hood latch.

Larger fuel injectors required for smaller than 3.1" pulley sizes.

Longer supercharger belt is required. Typical: 3.1"+ pulley needs a 685 belt, 3.0"-2.8" pulley uses 680 belt, 2.7" or smaller usually requires 675 belt

For installation of stage 2 intercoolers on 2004+ Supercharged GPs, we recommend our Alternator relocation brackets, cradle spacers and inlet turn down adapter (drive by wire only) for added hood clearance. 04+ Monte Carlos and Impalas will need the Alternator relocation brackets. Will not work with our L36 Supercharger Kit due to injector location.

Stage 2 core is made of Aluminum and weighs 8.9 lbs.

This kit DOES NOT work with our L36 supercharger kit due to injector clearance.

Awesome product

I was waiting for the restock. I got my restocked email early 2 days ago and ordered the IC and some other stuff and I got my stuff last night. Literally the next day!!!!! I was very happy with the product and FAST shipping. Not a single fin out of place on the core or heat exchanger. I've read others saying there stuff showed up bent or something and my stuff came packaged great. I'm definitely glad I opted for the billet fuel Logs!! Thanks again ZZP for great products and great service. Now gotta order more stuff for the build

Well packaged, quickly shipped and, with helpful instructions. Installation was straight forward on my 02 GTP. Everything fit perfect the first time even with my unconventional way of running the IC lines from under the blower. Could feel a massive difference in the car after installing it, more consistent power during hot days and hard runs. Would strongly recommend the intercooler fill kit with this, made life waaay easier when it came to bleeding the system the first time and keeping it topped up when I had a leak (line got loose far from home and had no tools). Many years down the road and with almost 50,000km on some parts I have had no issues with any of the many parts I've gotten from ZZP and can't wait to order more. As someone who works in a shop that heavily deals with all kinds of aftermarket companies, on road and off road, and installing parts across tonnes of platforms. ZZP by far has some of the best quality parts with everything you need to install them, most straight forward installation instructions and, excellent customer support for when things don't go as planned. Would 100% recommend ZZP to anyone.

2004 Grand Prix stage 2 intercooler

Good parts high quality. Old directions. Needs an update. I feel that this is a consistent weakness in that there needs to be consistent directions provided for all parts that are provided. Mine said silicone did not need to be applied on the supercharger side but I had a vacuum leak and had to apply silicone to get it to seal. Also the long bolt on the pull side was to long so I had to take about a 1/4” off to make it work.
