2014 Grand Cherokee 3.0L ECO-DIESEL
Easy install, 90 min. Hardest part was removal of stock exhaust. Absolutely no difference in sound, could even be quieter than stock, but definite improvement in engine operation. Smoother operation, during acceleration thru the gears. Added a K&N intake system and it is a totally different running vehicle. Wanted to try these before adding a Bullet tuner. I think I will wait to see how it pulls a 26' travel trailer before adding the tuner. Great value.
