Well, I can' say whether this helps or not. If it does, it's likely marginal but it's drop dead easy to install, is relatively cheap, is well made and fits perfectly, and it can't hurt. LIke RiffRaff's other specific products, it's well designed and perfectly made.

Works great and was easy to install

install was easy. i screwed up the first time and didnt lube the WHOLE o-ring so i kinda pinched one. first installed when i had the turbo and intake off to do up-pipes. easy! when i had to put new o-rings on i ended up taking the intake off and the cold intercooler tube for more room. still easy. CLEAN the head very well and get the WHOLE o-ring lubed up so you dont have the same problem i did. honestly i think it sounds a little better but i bought it for the science behind it. Clay was great and emailed me how to get a new o-ring on friday even though i didnt know they were closed (covid BS im assuming)

High quality component, not the easiest thing to install but worth it 100%

This thing fit perfectly. Install was easy and straight forward. I did this with the fuel crossover. What I noticed was my hpop readings were more consistent. The gauge didn't bounce as much. And the pressure was much higher.

Recieved this extremely fast and literally took all of 10 minutes to install, took longer just to find my wrenches. After driving around for about 30 miles definitely noticed motor now runs quiet and smooth.

This was one of the first things I do to my 7.3's. Smooths the truck down right away and seems to keep my injectors working much longer then intended. Thank RR

install was fairly easy. It took longer to take everything out of the way, than the actual install. I have big hands, so i removed the hot/cold pipes as well as the air intake all the way up to the turbo . Total time was around 15-20mins.

I put this on my 2002 Ford F350 7.3. I am glade i did, motor is smother and a bit quieter. Good deal.
