So my serpentine belt has about had it its cracked all over and i have decided to get a 15% cravenspeed reduction pulley and smaller serpentine from Outmotoring. My question is what spark plugs should I get to go along with these mods all i know i need a colder rage plug. Advice on the best plugs to get from Outmotoring would be helpful thanks!!!!

 

My suggestion on a brand is ngk...
As for heat range, one step cooler, which means the JCW PLUGS...not sure of the number off the top of my head, but when you look up plugs, the books will list cooper, cooper s, and cooper s with jcw....that or any competant parts person can get you "one step cooler" than the stock s plug if they know how to read the standard plug....

 

Ok on the outmotoring website i picked the ngk irdium IX it gave me two options standard and colder. It doesnt say what heat range or recommend what to get with the pully so i picked colder am i going the right direction i just dont want to order them then have the wrong ones im shure i could just go to autozone and get some but i figured it might better to get them specifically from a mini website instead of asking som kid at a car parts store who doesnt know anything.

 

You need a good set of NGK's one heat rang colder and the correct belt. (1379) or buy them in a package and you know you have the right things.

Ok thank you both very helpful

 

Sure the outmotoring site is fine...bought a few things from them...
Stock plugs for stock pulley, cooler or colder for the reductions.
I hesitate going to some of the big box places cause sometimes they are incompetent...a while back a person had a thread...got some kind of fuel saving plugs that were getting advertised a bunch at the time....(e-50 green plugs or something) was given the "cooper" ones for an S....struck the top of the pistons...wrecked the motor when the piston was damaged....
Thats why i do not hesitate to use our vendors.....and know 2 different ways to get the same part # when i get them locally to be sure!!

 

Very very true i could have done that lol not shure it would have saved me much $ but i didnt even consider that thanks again

 

NGK's
Stock-BKR6EIX
1 step colder BKR7EIX **What You Want**

 

Order a set of NGK -4285.

 

Check out our WMW pulley package, it has the pulley, belt and plugs.

We don't recommend the Iridium plugs as they wear out and fail too often. Our kit includes the reliable JCW plugs.

 

Picked up the Brisk Silver plugs from Alta.. haven't installed em yet but research showed pretty good reviews.

Anyone have any history or experience with em?

 

Just make sure you torque them down and check them often.

 

Ok and with these i dont gap them correct? just tourqe them down correctly with a tourqe wrench then im done? I got the colder range ngk irduim IX plugs

 

Which NGK? Four prong?

 

It doesnt give a part # on outmotoring that i can find so im not entirely shure i pretty much went off of what they offered nd what ive heard i heard ngk was good so i got those and get a range colder which i did i honestly dont know very much about plugs all i know is pull them out and tourqe the new ones in

 

From the picture i only see one prong

 

They should be pregapped.

 

You do NOT gap the 4 prong plugs, if you try you will ruin the plugs.

 

There is no need.to gap the single prongs either, come pre-gapped.

 

Perfect thts all i needed to know thank you

 

are a single prong Iridium....
The tip is very brittle, and TINY, do not try to gap!
Have used them since my pulley install, no issues.
