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?

 

Denso Products is a vendor for Denso Aftermarket just like your local Toyota dealer is a vendor for Toyota Corporate

The end user can not buy Direct from Denso only through a vendor


To make any aftermarket product it needs to have a really high demand to off set the start up costs.

Then just because a Product is Denso Aftermarket while it fits the vehicle it may or may not be built to the same standards as the parts sold to the manufacture .

This happens quite often where the parts can only be bought from the end product manufacture .

You either pay the dealer cost or not Do you get the discount from your dealer ??

A walk in parts department is going to charge more then the online dealer to off set the overhead

As for gaskets I had good luck with NAPA in the past now since they are trying to compete with the chain stores who can say so many products have been out sourced to 3 world countries with quality control hit or miss.
