As discussed in several threads..... Amazon "may not" be the best place to buy parts if you want to be absolutely sure you are receiving genuine parts
Note that in this article it includes automotive parts.
Rock auto is where many go for parts ....I know I have gotten bad spark plugs and likely a MAF sensor from Amazon . The MAF lasted under 2 yrs and the plugs upon research were counterfeit...I sent those back prior to installation.
The parts may work but may not have the longevity or performance of the real deal...just my opinion
Another source that I have doubts about is -Bay...... again, just my opinion unless you can trust the seller....
