The MMS Cold Air Intake Kit will allow you engine to breath easier and produce more horsepower. The MMS Cold Air Intake Kit includes K&N cone filter and our smooth walled intake tubing to reduce turbulance in the intake airstream. The intake kit includes everything you will need to install it on your vehicle including high quality stainless steel clamps, and 3-ply silicon couplers. Our cold air intake for the 3800 engines features a custom-made silicon coupler complete with intake air temperature sensor location molded in. This means no improperly-fitting grommets for the IAT to sit in. W-body fenderwell intakes feature a 9" long tube diameter K&N cone. All other intakes feature a 7" long 3.5" tube diameter K&N cone for space-constraint reasons.
Common questions about MMS Cold Air Intake:
Why is a cold air intake good for performance? Colder air is more dense than hot air, which means there is more air in a given volume of space. Making the intake charge colder means there are more air molecules traveling into the intake of the engine at any given time. The more air and fuel you can fit into each cylinder before combustion, the more horsepower the engine will make.
Why wouldn't you use aluminum tubing like the other cold air intakes out there? It's all in the name ... "COLD air intake". Aluminum has a high coefficient of thermal conductivity. What this means is that it is very good at transferring heat. Every second it sits in your engine bay, it heats up, getting closer and closer to the temperature of the air in your engine bay, which is usually well above ambient temperature, perhaps 50-100+ degrees above ambient. Now air is a good insulator, so it transfers heat much slower, so the air moving through the tube won't heat up by a large amount before it's ingested by the engine, but any temperature increase of the intake temperature at all would mean you are giving up horsepower. Our solution to this is to use an insulating material instead of a heat-conducting one. The tube we use is made of a nylon and polymer (both good insulators).
Don't the ridges in your tubing cause restriction to the airflow? Not at all. The corrugation of the tube on the outside is much different than the surface on the inside. The tube is made with a steel helix skeleton, so the corrugation is a result of it's design to be able to allow the tubing to be extremely flexible, but the inside of the tube is extremely smooth, and perfect for moving a large amount of colr air through quikly and without restriction.
Is there a risk of hydro-locking the engine if I have a fenderwell intake and drive in the rain? Unless you submerge the filter driving through deep water, there should be no adverse effects or risk of hydro-locking simply from driving your vehicle during a rain storm.
