OEM or after market?

Ive seen a lot of recommendations for denso COPs and Im interested, but how can you know they are not counterfeit? I see my two local auto stores selling them for more then my toyota parts dept sells OEM. Then i see this site. https://www.densoproducts.com/ Selling denso COPs cheaper then dealer OEM. But is that site really Denso, direct from the manufacturer?


I need the electrical plastic plug that plugs into the COP. Dealer parts 10$ each. Someone needs to make a quality aftermarket, but who?


ditto gas cap or just the rubber. mine dried out. Dealer 32$. Ouch.


Also manifold gasket. Are there any good aftermarket?

 

Go to Toyota. They are buying the parts by the 1000s. Plus they have little interest in selling counterfeit parts.

 

The Denso website recommends them.

If you go to the Denso website.
And then click Find my part.
Then select the part.
Then Buy Online

You will see DensProducts.com as one of retailers.

 

Tks. What about aftermarket gaskets? who makes good ones?
