I have a 1999 pontiac grand am. 3.4l v6 I need suggestions on a good cold air intake because im having trouble finding one.I just want to increase the hp and fuel economy in my car. if you guys have any suggestions on how to do this along with a good CAI it would be greatly appreciated !!Thanks!!
Harley Drive almost got it right.An aftermarket intake will do NOTHING for your car other than maybe offer some aesthetics. As for the rest of Harley's post it's NOT accurate. Most vehicles suffer from what's known as heat soak. sitting in traffic on a hot summer day is going to use more fuel. Having an IAT reading true temps will help your motor run better. This however is NOT done with a CAI it's done be taking the IAT off of the MAF and relocating it. This can only be accomplished by having an intake that's pulling in true temp air with a CAI such as an OTR or (over the radiator) and placing the IAT in the front as the air is being drawn in at the nose. Any airbox remaining in the engine compartment offers nothing. Changing only the CIA will still create heat soak so just put a KN in the stock box and call it a day.
check with junk yard and see if they have an owners manual for your car it is cheaper than dealer
simple fact - they don't work on injection systems in fact they cause the ecu to run a cold start program which enriches the fuel and wastes gas, if something as cheap and simple as an air filter increased power and gave better gas mileage don't you think the manufacturers would all fit them even as an option, also on lean burn engines the colder denser air would make the mixture even more lean leading to burnt plugs and valves, the ecu/maf/temperature sensor are all mapped together upsetting the balance would cause performance to deteriorate, the injection system squirts a measured amount of gas at each cycle so more or colder air would make no difference, unlike a carburetor which supplies gas continuously
It already has a cold air intake superior to any affordable intake on the market. It is possible to get a miniscule power increase you could never feel it at full throttle and near power peak but at the cost of poorer fuel economy, especially in the winter. Aftermarket intakes also have a risk of ingesting water and destroying the engine, as a friend of mine discovered a couple months ago.
