im wantin to know what is the best time miles whise i got 65k miles on my truck right now and i dunno if the guy did a tune up yet or not and so ya...

im lookin to get the NGK Iridium IX are those decent plugs i had denso Iridiums in my old truck and loved them...

now id like to try the NGK's any thoughts and etc please

 

i think the iridium's are a good plug. but for the money they are a little expensive. i have spent a lot of money chasing exotic plugs and have come around to the conclusion that the ngk tr55's are a good plug to run and the whole set is under 20.00.

 

I like my ngk tr55s as well. They seem to be a nice plug and won't break the bank.

 

I Was Told The 55's Are A Little Colder Than Stock And The 5's Are A Little Hotter. Im Running The 55's Right Now And They Are Doing Fine.

 

ACDelco Platinum's for me....I run a small gap with a Whipple...So far no probs..

I would have to say that there are a lot of over-priced plugs...Just because they're more doesn't mean they're gonna make your motor run smoother.. I would follow your service manual unless you have N20, Turbo or a blower...

NGK Iridiums are working good for me right now

 

ok diffrent question or well same thing but whats the diffrence between the following?

NGK V-Power TR55: 2.24 a plug

NGK GP Platinum TR55GP: 2.68 a plug

NGK Double Platinum PZTR5A-15: 11.71 a plug

NGK IX Iridium TR55IX: 6.95 a plug

id like to know how offten to change the plugs and etc....
i had good experences with denso iridiums but now id like to try something diff but well mainly NGK's

thanks

 

also power gains yes no maybe???? better on gas and etc???

 

anyone?

 

i dont really see power gains with them as much as just a great plug for a lot less money. wires. they could make some improvment if yours are bad. you might fell a small difference .
