I have learned to ALWAYS search a part number on Amazon and see what turns up. Recent savings for Jeep diesel, one relay $37 dealer, 4/$9.99 Am. Def fluid cap. $76 dealer, billet diesel cap & def cap $9.99 Am.
yeah but the problem with buying SO called OEM parts off Amazon and eBay and sadly many other places is
many of them are counterfeit products being sold as OEM or brand name
they come in same like packing have same like markings and such, but there Not real OEM products
and that is why there so much cheaper than OEM parts
there are tons of videos and like showing how there sold to look like original brand name products
so like most things in life, when deals are too good to be true, most times they are fakes!
and also consider, the risks on engine parts, a NEW engine is a lot of $$$ to save a few dollars on a filter or like part
sucks paying higher prices,(and yes dealer way over charge parts, BUT there are reputable online stores that sell legit parts cheaper than dealers,, if one is willing to do there homework, but AMAZON is not really one I would trust)
but in the bigger picture, quality matters in many things saving a few dollars that could cost you thousands, has to be a personal choice!
