1999 Ranger XLT 4X4 3.0 liter, 107,000 miles. The air filter system is already a cold air system, but will an aftermarket "cold air intake system" make much difference? Performance Chip has one for $85 Looks like it bolts onto the end of the intake hose from the throttle body and replaces the air box, etc. Simple enough.

 

Garbage. Replace it with the stock one which is 10X better than that HAI.....
