Just a quick question....

What are your guy's opinon on a better spark plug, (for both the 300 and the 400) the denso irridium,(Spelling sorry) vs the same style NGKs?

I am trying to make a decision based on performance, mileage, acceration, etc., Thanks for the input

 

ngk.

 

denso.





but only because I have em

 

I've been running Denso since last winter, no complaints, slightly better milage (24 MPG highway).

 

I went with the ngk because of price and they rock. If I wasn't broke that weekend I would have done the denso as I have heard so many good things about them but like I said I am happy with the ngk's.

 

hmm...denso....

 

Denso Power iridium are the best and theyre only around $100 for all 8

 

Denso.

 

ngk will do fine

 

NGK only cuz it's cheaper

 

Denso iridium...

 

Both are good plugs.

 

NGK

 

Its kinda like, whats better a Ferrari or Lamborghini? They are both a great choice, but I knew Densos had more reputation so I went with them

 

NGK.

Why some people would pay twice as much for Denso that performs the same.... is beyond my realm of understanding.
