wez_p Posted April 11, 2005 Share Posted April 11, 2005 howdi all, can someone please tell me where i can get the NGK stock plugs at a normal price?! so far i've had Partco quote me 9.50 each, DMS (another local motorfactor) quote me 12.66 each and then the local Toyota quoted me 13.13 each plus vat (this was actually for Denso PK20R11 which are apparently what have now replaced the NGKs according to them) i've been searching & reading and it looks like people are only paying £42 for a full set of DensoS!! and NGKs should be more like a couple of quid each, at most?! i'm also assuming that with just the Apexi induction kit and stainless cat-back exhaust, i don't need to go 'colder' just yet i'd really appreciate it if anyone can help me... wes Quote Link to comment Share on other sites More sharing options...

merckx Posted April 11, 2005 Share Posted April 11, 2005 The NGKBKR7E(6097) will be fine on your car, some say they don't last as long as Denso's but at that price you can afford to change them more often. They're a good price at this place for a set of 4 http://www.mx5parts.co.uk/product_info.php/products_id/236 Quote Link to comment Share on other sites More sharing options...

Aerotop Dave Posted April 12, 2005 Share Posted April 12, 2005 I used sparkplugs.co.uk, very quick and 'average' on price. Dave's Basic Spark Plug Guide NGK BKR6EP-11 (2978) - stock, Toyota fit these at the factory NGK BKR7E (6097) - recommended for BPU, but need replacing yearly at least (if you changed them at every service you'd be about right). NGK BCPR7ES (3330). These are the next one down (colder), but have been known to cause slight stumbling at idle. Equally there's a lot of people who run them just fine. Denso Iridium IK20 - stock replacement Denso Iridium IK22 - Good for 400 to 600bhp Denso Iridium IK24 - 600hp+ The Denso's last longer than the NGKs but cost 5 or 6 times more (and they don't last 5 or 6 times longer!). Fitting IK22s to a BPU Supra would be an expensive luxury over the 6097s or 3330s. Generally if you have a stock Supra go with 2978, if you're BPU go with 6097, if you're more than BPU then start looking at the Denso ones.

tDR Posted April 12, 2005 Share Posted April 12, 2005 Dave the NGK information in that guide you keep posting is incorrect m8. Quote Link to comment Share on other sites More sharing options...
tDR Posted April 12, 2005 Share Posted April 12, 2005 NGK plugs are not pre-gapped as such unless there is a tag at the end of the model code such as BCPR7ES-11 which means a 1.1mm pre gap. You should always gap these plugs with a set of feeler gauges before fitment (I've measured them at anywhere from 1.0mm to just over 1.1mm out of the pack!). For above 1.1 bar I'd gap to 0.9mm or less (down to 0.8mm) for the most efficient spark without risking it getting blown out from the increased cylinder pressure over stock. The colder grade stops pre ignition (the heat in the cylinder causing the plug to ignite the mix before the coil pack fires it) as it can withstand higher cylinder temperatures which result from increased boost. ^^ Some NGK info I posted on a recent thread relating to plugs. Also, BKR7E aren't copper but have a V groove electrode whereas BCPR7ES are copper but have a normal straight electrode. There is no heat grade difference (incorrect info in Aerotop Dave's post) between these two models and both would be fine in a BPU supe - the number 7 is the indicator of heat range... and 8 would be one colder again (standard is 6) so a big single'd supe would probably be best on BCPR8ES plugs.

Aerotop Dave Posted April 12, 2005 Share Posted April 12, 2005 Okay, I think I can see that now You're right too, I got that info from Supraforums but I've just checked another source and it is indeed all about the electrode. It's getting so hard to work out who the people are who actually know about stuff and who are those who simply pass the info on and sometimes get it wrong. Hang on... I'm one of those The problem is made doubly hard when you visit other sites because you don't know the background of the people. For example, I know CW knows what he's talking about, but if I was a visitor from Mongolia I wouldn't know that. Visit Supraforums and you haven't a clue who the Chris Wilsons are and who are merely Aerotop Daves. Quote Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted April 12, 2005 Share Posted April 12, 2005 would my NA use same plugs as stock turbo?? NGK BKR6EP-11 (2978) - stock, Toyota fit these at the factory or the NGK BKR7E Quote Link to comment Share on other sites More sharing options...
wez_p Posted April 12, 2005 Author Share Posted April 12, 2005 thanks again for your help here Merckx: the 2 places i'd found through Google (one of which was spark-plugs.co.uk) had the cheapest offering for the BKR6EP-11 at £10.47 each + VAT, but thanks for the Brown Bros details Mr Meldrew but now i'm thinking i can just go for the BKR7E and be prepared for any BPU stuff i do too then, so i'm gonna go back to try for them at Partco or Halfords and see if they got them in the induction kit plus stock exhaust upgrade mean it ain't stock anymore - right?

tDR Posted April 12, 2005 Share Posted April 12, 2005 BCPR7ES and BKR7E will be fine for your application wez_p. Gap them down to anywhere from 1mm to 0.8mm depending on the boost level you wanna run. You can get them at around a tenner a set of 6 from nearly all motor factors. BTW the plugs you've mentioned are always expensive (BKR6EP-11) as the P stands for platinum - these are a long life plug for extended service intervals, good for a standard car but not good for tuning. They are also pre-gapped at 1.1mm according to the tag. I'm not clued up on the NA cars as far as plugs goes but I'd assume they run a hotter plug as standard than a turbo... so a grade 5 likely but look it up on sparkplugs.co.uk to get an idea. Dave - No probs m8 just wanted to make sure people didn't get plugs based on incorrect info, as I personally prefer the copper core BCPR7ES and have had no problems running them in a manner of tuned turbo applications Quote Link to comment Share on other sites More sharing options...

Fifty Posted April 29, 2005 Share Posted April 29, 2005 Just got Laser Plat BKR6EP-11 for 7 quid each plus VAT ; this is cheaper than http://www.spark-plugs.co.uk they are £10.48 each. Halfrauds didny have any so went to APMotors Plympton.(haha price edited fron 110 doh) On the downside the thieves at Toyota chardged 12 quid for the 2 crankase hose I thought they were 2 quid each - gave him a nice scalding. 50 Quote Link to comment Share on other sites More sharing options...
