I am interested in installing an air intake kit on a 2000 XLT, 4.0L SOHC. Based on the various threads here, the two primary choices appear to be KKM and K&N. A big plus for KKM is low cost, whereas with K&N it’s the fact that it is a complete installation kit with a replacement intake tube and the kit is emission legal in all 50 states. I am tempted to go with the KKM because of the cost, but what concerns me is that many KKM users on this and other forums reported an unpleasant squeal at around 2,500 - 3,000 RPM. Has this noise problem been identified and successfully resolved? Does the K&N system suffer from the same noise problem? This is primarily my wife’s car but I drive it whenever we go on vacations and would appreciate the extra power. My wife also would like to improve the performance of the car, but unpleasant noises for her are a NO NO.
Another question I have is whether either filter kit will improve the performance of the car at high altitudes (say 8,000 ft)? Typically the car is gutless at this altitude.
