What spark plug brand do you recommend?

Planning to change soon - approaching 100K.

Thanks.

 

Hello there, research has shown that the factory Denso plugs are the best plugs for these cars up until high horspower.
Be advised that these plugs are expensive and anytime you see them under $10 each is because theyre fake.
Amazon and Ebay have fake ones left and right. If you choose to go down this route use legitimate businesses like parts stores/ dealer/ legitimate web stores.

 

Thanks. I have an O’Reilly’s nearby that does a great job and I like to support local businesses.
The good news is there are only 6 plugs and they last a long time!

 

Correct, they will last a long time.
Another practice I do is save the old ones, every once in a while I label them. I have two VHRs and old plugs have saved me in the past.
