Im looking into buying soem LS1 Fans. and i was wondering if i need anything else besides a Harness. Would i have to have anything else to get it running right without problems? And i heard someone talking about having a problem with overheating with ls1 fans. and...ya

How much hp do ls1 fans free up and how much colder does it keep under the hood with the fans.

 

made 5rwhp with the 20's on my yukon

 

PM White1, he makes a awesome harness and don't forget about a tune
