Great price and great product you can't go wrong with OEM parts solved my long crank cold start problem. Although only 128k on the originals, after 23 yrs they took a set. These were great and fast shipping.

This is the 2nd time i have used these o-rings from Riff-raff. I had previously taken my 1997 F-350 to a diesel mechanic for injector problems. They claimed to have installed new injectors on the driver side and told me the passenger side would need to be replaced. 1700$ per side.
When I replaced the injector o-rings on the passenger side 2 months after the mechanic did the other side, I did it myself saving the $$. I used riff-raff o-rings.
This was 5 years ago.
I recently started to have the same injector issues so I ordered new O-rings for all 8 injectors form R-Raff
I pulled all 8 injectors. The o-rings on the injectors that I had replaced were still in great shape, soft and pliable. I was able to pull pull them all off without any breakages.
The ones the mechanic did were crumbly and very worn. Clearly he used cheap inferior o-rings.
Definitely would recommend them.

As described factory International O-Rings. Excellent quality

If you dont want any issues, and only do the job once at the right price these are the orings you want to get.

Absolutely fantastic. Got er done drove thru the week seemed good. Had a cruise thru town and was gettin the beans. Now to fix the low boost issue
