THAT IS COOL. Wonder where those parts came from?

I was looking really close today as I degreased the whole bottom of the motor and cleaned really well everywhere. It looks like redoing the intake air box into a snorkel would not be too hard and vastly lower input air temp. Wonder what that would do to the ECM?

 

Not much, as the IAT updates it faster than an ex-wife can call her attorney. The IAT and the MAF values are part of the "weight of air vs. weight of fuel" calculations. It will adapt to maintain the stochiometric ratio. So adding a snorkle won't give you 10 mpg more or faster quarter mile times. But you may be able to do 0-60 in 3.8... gallons. Now if you were on the Autobahn at 130 mph plus, sure, might have some benefits. On stop and go traffic at 45 mph - not so much.

 

I attached mine with these push in plastic fasteners, don't recall if they were on the D2 or from the blister pack aisle at the parts store. Liner is a little short in front.

 

That DII liner is no where near as thick as the DI hood liner.
I saved my push button hanger plastic thingy things, I out them back in the hood.
My liner was sagging where it was not fastened.

 

The hood "scoop" on a RRC is for the HVAC system not for the engine.

 

The only time heat builds up under the hood is while sitting in traffic or moving really really slow, the cooling system is what keeps the engine cool.

 

Haven't had mine for years. It's a fire suppression blanket.

 

That's what I plan on using.

 

if you off road you don't want holes in your hood. it will release trapped air when wading. allowing water to get higher into the engine bay which means bad things for the ecu on a d1 or the fuse box on a d1 or d2.
