"Excellent radiator! Al, Marc & Jane are superb people to work with. They came to our shop and built a radiator that fit our needs! Had no trouble the entire season! Ran cooler than ANYTHING we've had in the past! Thank for the awesome hand-made AMERICAN product. Keep up the good work!"

"I've been racing Super Late Model for 19 years, running in 100 lap events to Saturday night short tracks, and I've tried radiators from inexpensive Griffen to top of the line C&R. None of them cool as well as an Al-Kul Performance Radiator! I would recommend it to anyone!"
