I would recommend this upgrade to every 7.3. So worth the money. Not only does it quiet down the engine, it is going to prolong the life of other parts as well for equalizing the oil flow.

Not to bad of an install, you just have to climb into the engine bay. About a 30 min install for me, wanted to make sure I didn't mess anything up. Seems to be making less noise on the rear passenger side and seems to be a little more responsive.

A friend, who is a very experienced diesel mechanic, recommend this product to me. Trusting his judgement, I ordered and installed the high pressure cross over line. It was an easy install, taking about 45 mins. I started the engine and immediately noticed it ran quieter. After a few mins, it smoothed out to a purr and has continued to eleminate any rough idle noticed before. It seems to be a bit more powerful and responsive. I have a 2002 F250 with the 7.3. I believe this addition has made a great engine even better.

had the fuel rail crossover installed for a number of years and really liked it. finally installed the oil crossover and immediately noticed it being quieter, running smoother, and seems to respond better with throttle application, should have gotten this product years ago!

Cant Believe the difference. noise in the engine bay using a Db meter, before was 120+db. after install, even just after start up the noise dropped to just below 100 Db. 20db is amazing after the truck had been
Running for awhile and had been driven it got even quitter. noticing the most difference in the cab. even notice it runs smother. amazing product couldn't be happier.

I don't know if it's doing anything, but it looks cool!

super easy install. make sure you don't mess o-ring on install. I feel like my truck is a little quieter. had a intermittent fluctuating idle that is now gone

I work on 7.3 here at the house. every truck that shows up gets this added to the vehical. so to say the least i've bought a lot of these.

if you are going to only do one upgrade this should be it. the truck is a lot quieter. idles smoother. starts better.

after adding this product the truck will be quieter, but after you drive the truck for a few days it will get even more quieter.

i've been running this product on my personal truck for over 190,000 with no problems.

As a backup keep you engine head plugs, the ones that you will remove, in a bag in your glove box. just incase.

for installation. you can do this job without removing any parts. to get to the plugs you just need a wobbly and an extension. then a swivel head ratchet wrench. job takes me less then 30 minutes, a stubby wrench is also helpful

Fit like a glove looks to be made from high quality material! Seems to have made a difference in noise but could be I'm just listening to the new turbo wheel installed instead of the rattles.
