PNR Stage 4 Intercooler Ice Tank Complete Package - 1979–1993 Ford Mustang (Fox Body)

The PNR Stage 4 Intercooler Ice Tank Complete Package for the 1979–1993 Fox Body Mustang is the ultimate cooling solution for high-horsepower street and strip builds. Featuring a 7-gallon half-moon reservoir paired with the high-flow CWA400 pump, this system delivers exceptional coolant circulation while maintaining clean trunk fitment.

Designed and manufactured in the USA, this half-moon tank mounts securely in the spare tire well and fits flush under the carpet (when not using the black and red ring cap). The CWA400 pump is one of the highest-flowing electric intercooler pumps currently available, offering near-EMP-level performance while retaining compatibility with factory intercooler bricks and heat exchangers. Correctly sized fittings are included to properly feed the pump while still allowing use of your OEM intercooler and heat exchanger configuration.

This is the premium option in the PNR Fox Body lineup, delivering serious flow capability, strong street reliability, and a complete, ready-to-install package for boosted applications.

Cap Options

All half-moon tanks come standard with an extra-large black cap. Optional upgrades include:

- Billet Aluminum Cap (Recommended): Provides the best sealing performance and long-term durability.
- Black & Red Ring Cap: Enhanced sealing with ten mounting bolts and external threads. Does not sit flush under carpet and must not be over-tightened to prevent thread damage.
- Black/Clear Cap: Available but may crack at the clear center due to trunk heat exposure.

For maximum reliability and sealing performance, upgrading to the billet aluminum cap is strongly recommended.
