I did a search on ceramic coating the intake and saw several replied, indicating that people had done it. No one said that it helped cool the intake charge. My question is to those people who have coated the intake, exhaust, up-pipes, down-pipes, did you notice any improvement? Did your 1/4 mile times improve, especially on hot days? I just had my headers done and the shop owner said the the coating will reduce the temp approximately 100 degrees. If that is true the intercooler pipes could really benifit with ceramic coatings. Before I go to all the expense of coating everything I would like to hear from you guys if it worked for you. thanks in advance
