I have having a hard time finding some NGK iridiums locally for the sr20det.
one place said it would take 2 weeks to get it in.
Also what is the part number I should be looking for. I am looknig for the BKR7EIX-11. what should the gap be or are they already pre gapped?
thanks
i picked 4 of these up yesterday night accually. you have to gap them to .08. BCPR5EIX-11 i think i got them for 8 dollars each. ill have to check my invoice. i can also get SR20 o2 sensors if you want.
yes please pmed.
Ok you have the heat range 5. It is great for NA engines. heat 6 is stock. Heat 7 is what you should be after or 6 if you have stock boost.
Don’t buy iridiums. They have a VERY small electode that is very easy to foul. Buy some coppers (give out the best spark) and just change them more often. For around 2 dollars a plug it is by far a better deal.
And SR O2 sensors are only 85 brand new at nissan if you know the right part number.

agreed … iridium are a pain in the ass to gap properly … the electrode gets fouled in no time …
I too would be interested in finding heat range 7s for SR locally…
Could someone else verify the info below?

BKR7ES-11. Partsource, napa, b to b they all have them
Yeah, partsource is where I got my BKR6ES-11’s. If they don’t have them on the shelf tell them to get them in. Or tell them to get them fast from another store. Any Crappy Tire should have them too, since Partsource and Crappy tire are essentially the same place - Partsource is owned by them.
I have a completely stock '91 180SX with a stock SR20DET engine. I haven’t had any major problems and haven’t gapped them. That’s probably a dumb idea. Maybe I should check the gap.
Is that gap 0.08 in inches? The stock plugs I have (which for some reason I kept) are gapped at 0.86mm or 0.034, and since my iridium replacements were so close to that I didnt touch them. Anybody else have an official source or line on what our plugs should be gapped at?
Ok first of all Partsource is owned by CT but their main supplier is Active Groupe. Ct’s main supplier is UAP. I do not want to get into the difference but they don’t use the same suppliers except for one.
With stock boost 6’s are a good plug (come stock in a redtop) however if you want to increase the boost to 12-14 psi i would highly recomend the 7’s/
The gap is .035 to .020 inches or .85 to .65 mm. However since you bought BKR6es-11 the gap on those is preset to 1.1mm hence the -11 at the end. They are FAR off.
Use what ever gap works for you. It all depends on how strong your coilpacks are and how much boost your are running and the temperature of the head. If you feel a slight miss at higher rev’s and boost, and the occasional popping of the exhaust tighten up the gap. If you have a hard time starting and running on a cold engine or you are fouling plugs, open up the gap. it is all trial and error.
Wow! Awesome. RS13, your post was very informative.
So now I know why my 180 is popping and misfiring all the time.
Now, peopl esay these plugs are very delicate. What’s the best way to end these carefully? A tiny set of needle nose pliers?
Also, what is the part I should be woried about? Damaging or breaking the tiny electrode?
Iridium’s???
Tap the lightly on the ground electode on a piece of wood. Check your gap using a feeler guage, not the hook of wire like a normal spark plug gapper. Just don’t go to far.
Yup I have the Iridium’s. Sounds like a great tip. Thanks man! That should clear up all the sluggishness that I’ve been having lately and pistol cracking backfires, not to mention probably improve my gas mileage and performance.
Any chance this might significantly reduce my exhaust noise if I have the gap out too much?
ummmm… its BCPR6-exi11 and most places carry them and gap them to .025 not .080 good luck trying to get a spark… :oops:
i decided to go with BKR7es-11 as well. CT and napa dont carry them. i get deals at bumper to bumper. picked them up today for 2.50 each
that is a great deal you got.
Partsource is 2.19 retail.
well i had better go pick them up there then. seems like im getting a little ripped off here :roll:
I pulled and re-gapped my BKR6EIX-11’s to a 9mm gap or so (used an SAE guage at 0.035") and wow, what difference that makes over the pre-set 11mm gap! My car barely chuggles or backfires anymore. I still get the occaisonal loud backfire (usually single loud pop) under heavy accel and I quite often get an exhaust ruffle when downshifting or <2000 rpm.
Should I lower the gap a bit more? I do have a performance straight-through 3" exhaust system.
Oh, and as a tip to everyone that dosen’t know which plugs to chose or use because NGK dosen’t list them on their USA or Canadian website, use http://ngkspark.com.au/PartFinder/spark_plug_vehicle_type.htm
Select “Japanese Import” and select your JDM special :’)
Oh yeah, I didn’t have any problems gapping my plugs despite the fact they’re pre set to roughly 1.1mm. Also, I found that those Iridium plugs are pretty durable. I’m impressed that after 5000kms of having them gapped far too wide that the electrodes and insulators were still in such great shape. They barely showed any signs of wear at such a horribly wrong gap size. Go Iridiums!
awesome.
no more questions from me
reeskm hows your car running? i just picke dup some 6s but on my last sr i put in 7s. just want to be sure before i put them in.
carry,
put 6’s if you plan to run stock boost on your sr/ca or put 7’s if you plan to turn it up a bit.
