Just buy the dang thing. Gave my truck a quieter idle, smoother acceleration, and better throttle response from a roll. You may have to muscle it in a little but not enough to were its a pain.

Fit perfect,good quality.It did seem to make off-idle throttle respones a little bit more snappy,idle basically stayed the same,overall happy!

Quality product however I had to muscle it to make it fit

Did not come with the plastic caps on
the ends, in other words not sealed

95 F350 7.3 WOW!!! What a total difference in the idle & it's much more quieter... I've should have did this a long time ago... Easy to install,, Thank you Riffraff diesel.....

This is a must for every 7.3 out there. It balances out the oil pressure on both sides of the rail, like it should have been from the factory. High quality product, easy to install, took me less than 10 minutes.

Good quality. Idle seems a little smoother. ICP isn’t jumping all over the place now. Not sure about throttle response since the old gal isn’t stock anyways.

Great product, cheaper and higher quality then the others out there, and looks a ton better then the braided crossovers in my opinion, and helps quiet the truck down during Ideal!

Really quieted my truck down, especially at idle. Seems to idle smoother with my 250/100's. Makes an awesome budget friendly upgrade that can be done in literally less than 20 minutes

Perfect fit, easy to install, noticed a difference immediately, idles a lot quiter. Seems like I have better acceleration also
