My 01 24V had about 250K on a set of 275's. They were noisy and had a slight miss on a cold morning. After reading until I was crosseyed about every possible type/size/variety of injector, I bought the 75HP 8 holes. What a difference! Brought the old 5.9 back to life. My first 300 mi. trip netted 22.6 MPG at 75-80.. About what I got with the 275's, but with a lot more low down usable power. I have a edge EZ, which is on 1, versus 3 on the 275's. These smoke a little more than I like on 2 and a lot more on 3, just s slight haze on 1. Exh. temps seems better. All in all I would rate these as very good, well worth the money. Good power, turbo spools much better and my motor is significantly quieter. Next test.. My 2006 Alpenlite 5th wheel @ 11,500 lbs.
