Buying ignition parts from Amazon

Never had fake parts from Amazon. I look up manufacturers part number and search/purchase from part number. BUT, their return policy is very good.

EDIT: Carefully read the reviews. I find most bad reviews come from poor packaging, damaged shipping or obvious returned/used parts sold as new.

I don't think your strategy is as good as you think it is.

Read about how Amazon warehouses commingle stuff in the same bins from the OE and 3rd party vendors.
 
you buy whitebox stuff on amazon to get cars out the door tomorrow.

if you want OE stuff there are many trusted retailers with much larger selections for that. as for plugs if you avoid NGK chances are you won’t get burned let’s be honest
 
Not worth the risk. There are several barriers of entry for a seller to get on Amazon to be able to sell automotive parts, but once they're in there's not much QC to validate authenticity. They can easily re-box generic parts as OE and feed it through the distribution network and likely never get caught simply due to how large and bureaucratic Amazon is.

To get caught, they would need to consistently be getting complaints and have it get reported where a trend can build. This is difficult because even a professional mechanic may find it challenging to prove. It's easier for them to just file a return and so it may not count as a data point. Not only that, but the automated approach Amazon takes to their customer service means that the reps are encouraged to simply process a refund rather do any real investigation. Critical thinking is NOT encouraged at Amazon's lower levels. That's why even as a customer, if you have a support request that's out of the norm, it'll be incredibly difficult to chase down. Even if the customer service guy cared enough (haha yea right) to help you, their hands are tied to what they can actually do.
 
I put some chinesium coil packs on my 05 prius. They were marketed as generic and I got what I deserved. They worked well for 5000 miles then one crapped out magestically. The car hated its sudden-onset misfire so much it switched to electric-only and shut down after that was depleted.

Ripped them all out and got some used Densos that I think were genuine.

If you get a knockoff exotic metal plug you'll likely get something that runs, but, jeez, the little tips can come off and smash your valves. Go with rockauto or an online franchised dealer.

For a lawnmower, maybe a little different. The parts pipeline is so contorted on those anyway there's a good chance of having good stuff mixed in, or at least the same stuff with different labels.

Maybe it's just Toyota's that hate non-Denso parts, or something?
