As the title says, "I have given up." After searching for countless hours on this site, handfuls of other honda based sites, including the www in general, I have just given up. Oh, and this doesn't include the amount of time i've spent on the phone. So I would have to say that I deserve some sort of an award for my search effort. I just can't figure it out. Every source I find either has something different from the last source(s) I found, or the particular info makes no sense whatsoever. I tried to do it alone and failed. The truth is, i'm running out of time. Import Face Off is in two weeks. So now i'm asking.

First, my car is a 91 Acura Integra with a first gen B16a. Yes, I have the whooptie doooo PR3 ecu that requires dual O2 sensors.

Anyhow, now that we've gotten that out of the way, i'll go ahead and ask. Okay, which racing spark plug will get me one step colder than stock? Then, how can I verify that this particular spark plug is one step colder? On top of that, how do you describe the type of spark plug that you recommended me (i.e., racing plug, stock replacement plug, etc.)?

I prefer an NGK, but I won't argue with whatever works. I will be spraying my first gen B16a with a 75hp wet shot. I have looked into the ZEX plugs, but I can't get my hands on them quickly enough for the Import Face Off event.

Thanks in advance.

 

BKR7E(S) is 1 step colder

There is a good chart for NGK plugs here and lots of good info.

Can I get these at a local parts store? (i.e., Orielly's, AutoZone, CarQuest, NAPA, Advanced, etc.)

Do you think that there is any disadvantages to not running the ngk race plugs on nitrous? I am assuming there isn't any disadvantages.

By the way, thank you for replying and helping me.

 

If I recall correctly, the stock B16A plug is a BKR6E-11, so you'd want a 7 range plug if you're shooting for one step colder. Most people simply move to the BKR7E(or BKR7E-11, which comes pre-gapped at 1.1mm), which is the same plug, only a step colder. Both the stock plug and the BKR7E are copper resistor type plugs with a projected tip.

In the past, I have run "racing" NGK 8's(R5672A-8) that were essentially a similar style plug, but in non-resistor variety. These plugs worked well for me, but when i tried to find them in a 7 range, I wasn't able to get the same plug. The closest thing I could find was a R5671A-7, which turned out to be a similar plug, but the tip wasn't projected(it sat slightly recessed in the end of the plug). I used a couple sets of the R5671A-7's with no problems, but I figured the stock plugs use projected tips for a reason, so I switched the the BKR7E's.

The only difference I can tell between the normal plug and the "racing" plugs is whether or not they are resistor-type plugs. These plugs are meant to minimize or eliminate RFI(radio frequency interference) between the ignition system and other in-car electronics. I don't know whether or not this is still an issue in modern cars but I, and many others, have run the non-resistor NGK's without problems. As for availability, you should be able to find BKR7E's or BKR7E-11's at any NGK dealer, although most nationwide chain stores will usually stock them by the NGK stock number rather than the actual part number of the plug. The stock numbers for the plugs mentioned above are:

BKR7E 6097
BKR7E-11 1283
R5672A-8 7173
R5671A-7 4091

Availability of the non-resistor races plugs might be a little harder, but most online merchants I've seen do stock them. All of the plubs mentioned above average around $2/per. You can plug the part numbers in at sparkplugs.com if you want more detailed information on most NGK plugs.

Hope that helps.

 

Okay, I just got back from AutoZone and checked to see about getting either a set of BKR7E (6097) plugs or the BKR7E-11 (1283) plugs. They had a listing for both of them, but they didn't have them in stock.

I'll have to pick up a set tomorrow from another parts store. I think that if I were to go with the 6097 plugs, i'd gap them to .035" for nitrous.

Thanks for all of the help guys. I think i've learned enough here to safely say that I know what I definitely need. Thanks again.

 

i didn't think autozone carried ngk. i know they always have them at advance auto parts, or it may be oreilly's in your area. http://www.partsamerica.com

 

I've found that the NAPA around here usually has them(the BKR7E's) in stock, while Kragen/Checker , Pep Boys, and Autozone are usually out.

 

I'll have to go to Orielly's tomorrow. I sure hope they have them. If not, I can simply try somewheres else. Not a big deal. The most important thing is that I know what i'm looking for.

I'll pick up two sets, and if I get the 6097's, i'll gap both sets to .035in., or if I get the 1283's, i'll just put them in.

Again, thanks for all of the help.

I would just regap them regardless. The gap can narrow from the plug shaking around in the box.

 

i have used the NGK 4091 for heat range 7
NGK 4554 for heat range 8
NGK 5238 for heat range 9
All of which are good racing plugs and can be found a advanced auto. good luck

 

non resistor plugs could cause interference in all sorts of electronics.. i wouldnt recomend them

i use ngk bkr7eix, they are iridum.. they last about 10x longer than the copper plugs and work fn awesome. they are around 8-10 bux each

 

So you're saying these plugs don't have resistors?

Do my stock plugs have resistors?

 

most of hte ngk racing plugs are not resistor type.. stock is resistor type.. you need them to be resistor type

 

Does it help if I have an MSD 6AL ignition?

What about the ZEX plugs for nitrous? Are they resistor type plugs?

 

Okay, I found out that the ZEX plugs have resistors. I know of many race cars using NGK plugs and haven't had any issues though. I mean, it's not like it's a do or die thing such that if I used the BKR7E plugs my car will start doing all sorts of weird stuff like a high rpm engine misfire.

This shouldn't be that critical of a deal. Right?

 

some people get away with non resistor plugs, but they can and have casued issues with dataloggers, aftermarket ign systems, etc...
