I have a 2016 CX9 Signature. I want to know what are the best sparkplugs for this vehicle.

 

Stick with the factory NGK sparkplugs

Can I use this one instead of the factory one?

 

Why would you even think about deviating from the factory plugs?

 

It's your car; you can do anything you want.

Check the NGK web site. They do not list a spark plug for our cars. Apparently our cars require an original equipment plug renewed every 40,000 miles. Buy them from any dealer, local or on line. No one has written about using an aftermarket plug that might be close enough to original. If you find one that fits, maybe try it and let us know the results.

 

2016 was the crossover from the V6 to the 2.5 turbo.

Specs for Australian Market

V6 plugs are LTR6BP13

2.5 turbo is DILKAR7M8

 

Dealer plugs are $$$$$$$. 22 a piece for a damn plug. I will shop online to get them as cheap as possible

 

Buy from a reputable source, there are a lot of counterfeit plugs on to be had online.
