Replaced glow plugs, harnesses and gaskets, I didn't expect any changes other than easier starting in cold weather. I was surprised when the truck ran smoother and I no longer have an occasional harsh 3rd shift, I can only surmise that possibly the old harnesses were breaking down and not always sending proper voltage to injectors. 290,000 on '97 7.3

Item was packaged in International bag. Perfect OEM replacement.

Great product, purchased 2 and both came in packed well, nothing broken. Generally easy installation other than having to replace the gasket and both harnesses without taking the clamber cover off. ( passenger side )

'95 F250, 252K, only second time for check engine light, driver side UVC burnout of glow plug wires. What a stink! Fixed with riffraff OEM harnesses, gasket, and external pig. Runs like a pretty blue truck now. Go to riffraff first whenever one of my 7.3s needs money thrown its way. Oregon company for my Oregon trucks.

Just installed this on my truck to replace a burnt up harness. I wanted to get a good quality oem harness so i dont chance any poor quality parts messing up again. RiffRaff definabtly has the best price for most OEM parts! Fast shipping too!

Cant go wrong with OEM stuff. Fixed my melted wiring problem.

Perfect fit and top quality product. I will be buying from again.

Clay has a great price and his shipping is very fast. I replaced the after market under valve cover harnes with these to try and get rid of a rough idle. They worked great.
Thanks Clay

Came on time, harness fit good. Would recommend.
