Kind of a newbish question, but has anyone tried buying them from eBay? I'm a little skeptical on buying engine parts from eBay and would just like some feedback as to their quality.

 

NGK is a quality brand. OEM for Honda, Mazda, and Subaru.
I'm no fan of FleaBay, obviously look to see the sellers rating and how many products they have sold. Don't forget to compare pricing to RockAuto(discount code 90766617475558 or 91319925412898 good til 6/17)

 

+1 for rock auto. Good pricing, fast shipping and awesome customer service.

 

Buying them from eBay is the same as anywhere else, and its not eBay that sells it to you, its the seller.
