DDM Works Cold Air Intake w/ Heat Shield

Heat shield, 3 mounting nuts with lock washers, foam air filter.

The install is very easy and straightforward. Remove the old airbox, and use the holes that already exist in the fenderwell to install the heatshield. The heatshield has 2 holes that attach to the lower bolts on the MAF holding the intake up as the original airbox did. The heatshield doesn't completely isolate the air filter from exhaust manifold/header heat but does keep a majority of the radiant heat. I have a stainless header and after long periods of driving the heat shield would be hot to the touch but the air filter a few cm's away was as warm as anything in a normal engine bay.

There is one MAJOR PROBLEM with this intake and that is the sponge air filter. It's OVER-OILED and when the car sits after running the excess oil in the filter drips down on the fender and more importantly pools up and runs down the intake tube into the MAF and down the engines throat on startup. Then the oil proceeds to foul up o2 sensors and help more carbon stick to your rear bumper where the exhaust exits. by using spacers on the MAF-to-heatshield bolts I created enough space to put in a more traditional cotton cone filter and tossed the DDM works foam oil sponge in the garbage. The spacers also helped keep the air filter further from the hot heatshield. This intake should really be much cheaper than it is (over $100, seriously!?). All you can really use is the heatshield and even that isn't perfect. The airfilter supplied does more harm than good to boot. The only way I'd recommend this product would be if it were $20 and only included the heatshield, otherwise it's a ripoff.
