I apologize in advance if there is another thread about this my phone won't let me search the threads for some reason. So i was wanting to know if anyone has had any problems out of their stock intercooler? In the beginning of February my stock intercooler cracked the back and drained alot of coolant into the cylinders which caused me to do a complete rebuild. I chose the Lightning Force Performance intercooler this time. It was a bit pricey at $600 but it looked better made than a stock one. Another question, I have a moroso expansion tank for the intercooler what do you guys recommend to run in there as coolant? Any specific type of antifreeze? I appreciate any answers.
