Any benefits/disadvantages in running one step colder spark plugs for NA setup?

 

gonna give you a plug number, no questions asked. R5671A-8's, no further questions.

 

Is that a NGK part #? what is the heat range and is it good for NA setup?

Yupp, thats a NGK #, depending on how much advanced timing and compression ratio your gonna run depends on your heat rate, if your gonna run an All Motor LS, then go with a 7, but anything else like a built B16 GSR or Type R I would recommend 8's, use the R56718-8

 

Im runnng All Motor H22 with ITBs setup, what do you recommend?

Thanks man1

 

R5671A-8

 

dam where were you last week
lol

 

generally speaking, you want to run the hottest plug that you can without signs of detonation. NGK heat range #7 is the most common plug for naturally aspirated setups. Of course different setup's will require either a step colder or hotter depending on various conditions.

Not to thread jack... but how are those RM plugs working out? I see you're a RM dealer.

I just got a set of these plugs with my cams and will be dynoing them tomorrow back to back against some NGK's... stay tuned.

Whats so special about the R5671A-8's? According to NGK they have a resistor in them hence the "R".


I use NGK BKR7E on my Allmotor B18b. I used them too on my old nitrous motor.

 

well they say its a copper race plug ...racing does mena fast right

No but copper is a good conductor!

I havent done the research but if you ask most of the all motor guys on H-T they will probably tell you that plug, I think DTR runs this plug, I know a bunch of other tuners recommend this plug also. I know people have posted up on that plug before, give it a search if your interested more.

 

How easy are they to buy? Can you just go to Advanced Auto and get them or do you have to order them?

 

Most places stock them, they are only like $1.70 somethin a plug, your not gonna pay more than $10 for a set, I know where I buy them from they usually have them (Napa Auto Parts) if they dont it only takes like 2 days to get them, check it out.

 

I have the ngk v-power temp 8. Spoon uses them on their race cars.

I'm running the same plugs in my high comp LSVTEC, NGK stock number 4554. Didn't notice a difference going from the BKR7E-11s though.

 

i have a ls vtec, ctr pistons , stage 3 cams
are 8's good for me?

I run 7's in my crx . I broke in a set of 7s' and then a set of 8's on the dyno and made 8 pulls with each and the power didnt change enough to run anyone over the next..

 

running 7's in my motor too
