There are a lot of spark plugs to choose from, i am currently running the NGK-TR6's and was wondering if i should maybe go with a different plug for my application. I want to have fresh plugs in when i get my dyno tune at REM. Also plan on buying a couple of goodies when i go down there. Possibly some shackles and maybe a blower pulley.

thanks

I am running Denso IT-20's in my truck and I like them a lot but they are expensive. I had TR6's and they ran fine but they have a rough idle.

If you have the cash, go with the Denso's.

 

Talk to Paul at REM and see what he suggests for brand **and** gapping.

good idea, ill give him a call

 

bref 7 or denso it-24

 

who makes the bref 7 and where could i buy them. whats the difference between the it-20's and 24's. I ran the 22's a while back.

 

Here is a bit of a guide i think the denso's are alittle more wide ranged that what is shown but gives you an idea. I run denso's and see about 13-14 psi and love them!

 

i agree i loved the denso's but not the price. that chart is perfect, it gives me a good understanding of the plugs that are out there. I think ill go with the br7ef for right now but if i increase my boost 2# more i guess ill have to fork out the money to buy the 24's.

thanks
kurt

 

where did you guys buy the br7ef's from. having trouble finding them in the local part stores (AutoZone, etc.)

 

Try Advanced Auto Parts

 

Great chart Brahmus. Thanks!

 

found them at napa for 1.85 a plug

 

I'll accept the thanks but that is Tampablack99's chart.

 

I run TR6's and I see around 16.5-17 pounds of boost and the truck idles good and runs great. No need to spend so much on plugs, just replace them once a year, and get a good tune- IT's ALL IN THE TUNE.

I have always ran iridiums. This is very unscientific, but with my Denso
IT-22's in the truck, it seems that it will take approx 2 more degrees timing WOT without getting the dreaded ping. Admittedly, we are also in a period of terrible air, so it could be from that.

In the past, I've tried NGK TR8IX & TR6IX.

I'll probably stay with the Denso's.
