That's a really good gain. It says it doesn't replace the plastic models. Were your stock ones plastic?
My 2006 6.2's have Mercruiser 863416T flame arrestors which are plastic. I see Mallory makes one that replaced those but have not read any reviews where it made an improvement. Did you try any back-to-back test runs?

Those look just like the style that I installed. I can't see how they would just bolt on as at least the studs would need to be longer to account for the larger filter height. I would get a confirmation from them before ordering.
If they do then it would a lot of time.

The studs that hold the throttle body down are actally two pieces. The upper cylinder unscrews from the throttle body stud. The throttle body stud is 6m and I just took a 6m union and mig welded it to a 1/4 inch threaded rod. That became the new upper stud for the air cleaners.
The other issue was the throttle linkage. If you simply tighten the air cleaner to the throttle body the linkage will hit the base. I made a one inch thick adaptor out of 4 inch diameter pvc pipe cut on a power miter saw. This spaced it up and out if the way of the linkage. It also gets the air flow straighter into the throttle body instead of that 90 degree turn. I think I will play around with spacer heights to see if I can almost turn into a velocity stack. I have more than enough height under the sunpad.

I would really like to see pics of your setup Coops. Isn't PVC flamable? I know the plastic they use is something other than pvc but not sure what. This would definitely be a neat how to write up with pics if you had time.
Thanks.

Sub 50 degree temps this weekend...the boat stayed covered.
I will get some pics this weekend and if the pvc melts you have other problems...major problems!
Fire, fuel, booommm.
