Customer Reviews


PNR intercooler reservoirs are designed and made in the USA.

Intercooler tanks for the 2005 to 2014 S197 mustangs. Our tanks come in a variety of sizes to meet your needs. The range from 5 gallons to 12 gallons.

These tanks are to use with a external pump of your choice. Anything over 800 whp and any type of street driving we recommend the CWA400 pump that we carry. The internal pumps are more for the track only cars that dont get driven for long periods of time.

The install kits work with the factory supercharger and upgraded superchargers.

Each install kit will come with two choice of fittings of your choice, (12an and 3/4″ work with the factory and aftermarket superchargers. 12AN is a fancy version of the 3/4″. The 1″ and 16AN is usually for turbo and centrifugal supercharged, or modified intercoolers.) 50 feet of safety insulated heat hose that is made for this purpose, nylon clamps, insulated straps to hang hose, relay and inline fuse for all pumps, a brass ball valve and drain setup, stainless hardware for everything.

ATT: EMP pump purchasers. When using the 12an or 3/4″ hose and install kit, the pump recommends a 1″ or 16an feed. So the 2 feet of 1 inch hose with the reducer to 12an or 3/4″ is highly recommended. Feed port should be 1″ or 16an. Return should be same size as your intercooler and heat exchanger. Both 3/4″ and 12an will work with factory OEM. When purchasing with EMP pump with factory intercooler/brick choose 16an feed, 12an return, 12an hose and install kit. Straight or 90* fittings are your preference.


We have a few different caps to choose from under the options. First is our 6″ standard black and clear cap that is nice because it allows you to see the coolant flow. Next is the Xlarge version of that cap with a 8″ opening that allows you to see through. These caps are nice, but they dont hold well to antifreeze well. Some last a year before cracking and others last multiple years. We carry both of these caps in a solid black textured pattern that hold up to anything and wont crack.

Next is our black and red ring with clear center. The clear center on these caps are made of a better material that holds up to the antifreeze. We have never heard of the clear center cracking on these. These caps are one of our best sealers and do not leak. We use a custom cut gasket on these to make a great seal.

Black hinged cam lock cap is a good option for race cars. They make it easy to add ice. They have a nice gasket on them as well, but will leak past the oring if filled too high.

Billet black aluminum cap. This is our best and nicest cap we have. We tried about four different types of billet aluminum caps and the ones we carry are the best by far. We do also have a custom gasket cut for these as well. These do not leak also.
