"cold air" intake... What type of IAT Temps are you seeing?

His so-called cold air intake pulled under hood hot air into one of those crappy open element window screen oiled air filter. I bet the small debris his duramax engine is chewing on doesn't help longevity much!!

I have since looked at many aftermarket so-called cold air intake systems and hence my ls 68c10 doesn't breath through one of them.

I came back from the GM Desert Proving Ground to design that air induction system for the GMT800 models. It is still in use.

I'm not a fan of the aftermarket systems.

So what do we do to adapt these old trucks to the LS intake and not have the hot engine air temps for intake air?

I switched the battery to the other side, k+n intake (tube only) and the stock 2001 silverado air box with a dry AEM air filter. When i get a break from my house from hell i will put a hole through the radiator core support and make a air intake tube to go out to the grill opening and seal off the stock air box opening that went to the passenger side inner fender.

You've got to get to where the cool air is: either building a dam as was suggested here or getting out in front of the radiator support.

The good news is the benefits of the cooler air offset the increase in flow restriction for any ducting that you have to add.
