FJC’s Extreme Cold™ boosts the performance of your automotive air conditioning by lowering duct temperature by over 15%.  See our case study here which confirms the efficacy of this claim.  In addition to the “colder cold” coming into your cabin, you will also be conditioning the O-rings and rubber components of your system, helping to seal leaks in these areas.  Extreme Cold™ also extends the life of your compressor, reduces friction, removes moisture and keeps your system running smoothly.

Part #501 offers Extreme Cold in a convenient 22 oz refrigerant charge.   Our all-in-one design includes an attached charging hose and gauge to simplify your AC recharge.  Also available as a refill, without the hose and gauge—Part # 502.
