Hello guys,
Im planning to replace my spark plugs soon (within 2 weeks) and I came across a web site (STIKILLER.COM) where I saw NGK BPR7ES spark plugs for $14 each. I wanted to see if anyone knows if these are ok to use on an EVO VIII. I know buying from the dealer, I think I paid like $22 or so each. Please let me know if these are ok to use. Thanks.

 

NGK platinum BPR9es are the ones i bought 4 bux a piece

 

BPR7ES is regular copper plug, it costs about $10 for 4, you sure it's $14 each?
dealer sell iridium plug for evo thats why it's $22.
and please do a search, there are plenty of info about spark plugs.

 

FYI 9s are 2 steps colder - thats a lot. Even with all the mods I have I run only 1 step cooler. For stock or close to stock use 7s.

 

STIKiller.com sells them for $14 for a set of four, not each. Keep in mind that these are copper plugs, which will have to be replaced every other oil change or so. The ones from the dealer are iridium and will last much longer. However, $22 each from the dealer is a ripoff; NGK BPR7EIX iridium plugs are available for under $8 each.

 

Yup it is a set of four for $14. Thanks for the feedback guys.

 

Ebay is your friend, get the Iridium's. How often to you guys change your Iridiums?

On my bike the owners manual says 16K but I changed them at 8K and noticed a difference, after my buddies bike with the same Iridium NGK's wouldn't start at 9K!

 

im confuse now!
so, which one are the rite spark plug?

thanks for the info!

 

Evo 9 uses ILFR7

Evo 8 uses BPR7ES or BPR8ES or BR7ES or BR8ES , you can go 9 but thats for like 400hp and up....

if u want a set i have a few sets for sale... just PM me...

 

Just wanted to add that stikiller.com is a great company you may also now them as GSC.

 

With p/n's ending in "X" being the iridiums.

 

You can go to oreillys and get those same plugs for under 10 bucks. I think I paid 7 for all 4.
