Denso Vs NGK's
 

Would people care to share what they think about the pair ?:thumbsup: I currently have a set of NGK TR 6 in my truck but i think its time to change them out , and have been leaning toward the Denso. BUT my question is ARE they REALLY worth all the money???? I see JL was haveing a sale on them. If so what kind plug should i get in the Denso's i am running a # 5 lower pulley.

For my 4# I'm running IT20s. 6# is IT22s. So I think with your 5# IT22s would be your bet.

I like my Denso's....quality and a price for a piece of mind imo. But there will be guys in the 11s that swear TR6s are just as good and not to waste the extra money and there will be guys who say the Densos are worth every extra penny....

There is no comparison IMO

Denso's all the way
Use IT-22's, you will not regret it,
and just for the record I picked up 3/10ths Et and 3MPH top end with Denso IT 22's compared to my pryor best ET's using TR6's.
Don't know if it's the Denso's or not, but it happen.

I run 4lbs of xtra pulley 24/7, and it runs perfect.
I sometimes run 6lbs of xtra pulley and it runs perfect.
I run Juice with both these setups, and it runs perfect.

PS
No other plug idle's better,
has less misses,
or takes as much heat out of your cylinders

I agree totally!!:rocker:

whats the difference between the it-20's and the it-22's? I think JL has a deal on the it-20's right now...

thanks

:help:

The IT22s are a colder plug for higher boost applications if I'm not mistaken....

IT 20's:thumbsup:

The IT22's are a colder plug. The are usually for a 6# or higher and the IT20s are good for a 4lb'r.
