hadyn Posted June 2, 2005 Share Posted June 2, 2005 Which plugs are best suited to a BPU spec supra?Denso IK22 or Denso IK24s?I'd have presumed the IK24s would be the one to go for?? I think i've got around 380ish bhp @ the fly Link to comment Share on other sites More sharing options...
Alex Posted June 2, 2005 Share Posted June 2, 2005 IMO IK24's Link to comment Share on other sites More sharing options...
SupraTT2004 Posted June 2, 2005 Share Posted June 2, 2005 IK24's All day long. Link to comment Share on other sites More sharing options...
normore1 Posted June 3, 2005 Share Posted June 3, 2005 I am curious why everyone is saying IK24. I have been running IK22's for about three years at BPU (1.2-1.3 BAR) with no pre-ignition or detonation. After 10K miles on my IK22's the plugs are still in excellent shape with normal brown to grey electrode colour indicating proper heat range. The IK24 is a pretty cold plug at two steps below stock. In theory a colder plug will foul easier and will take longer for the engine to warm up while also running rough. I would be happy to accept that the IK24 is a better choice at BPU level if someone would justify with some reasons or photos showing IK22's that have insulator damage or other evidence of it being too hot a plug.

Alex Posted June 3, 2005 Share Posted June 3, 2005 It's a safety margin thing...for me the IK24's never skipped a beat at idle (cold or warm) and so it cost me nothing to run the colder plugs...also with so many ropey Intercoolers out there I'd rather have the colder plug.

hadyn Posted June 3, 2005 Author Share Posted June 3, 2005 Finally, I know its been asked a million times before, but all denso ik's come out of the factory with a generic set gap dont they? They're not pre-gapped for any specific applications? Link to comment Share on other sites More sharing options...
Alex Posted June 3, 2005 Share Posted June 3, 2005 They come with a set gap that cannot be/must not be altered. IK24's basically have a smaller gap than IK22's (and some other adjustments) Link to comment Share on other sites More sharing options...
terribleturner Posted June 4, 2005 Share Posted June 4, 2005 I throwinga spanner in the works here, but im runing 27's and never had a days trouble with thm (touch wood). Link to comment Share on other sites More sharing options...
Gamer Posted June 4, 2005 Share Posted June 4, 2005 I was going to post that myself.... I am Running 27's too. Link to comment Share on other sites More sharing options...
V Posted June 7, 2005 Share Posted June 7, 2005 A quick jump in: What's suited for mine? now going de-cat with fmic. I assume IK24's as well? Cheers SV Link to comment Share on other sites More sharing options...
Alex Posted June 7, 2005 Share Posted June 7, 2005 IK24's are best for you too V. Partco in Norwich or PANKS will get them in for you at a good price. I would have thought the cold start and idling on IK27's would have been poor and they would get fouled easily. If they work for those that have them then great, but I see no need to run that cold a plug unless you're running over 1.5bar. Link to comment Share on other sites More sharing options...
V Posted June 7, 2005 Share Posted June 7, 2005 Cheers. What about NGK's? Are there comparison ones by them? I belive some 200SX guys have had problems with the Denso's. Regards SV Link to comment Share on other sites More sharing options...
Alex Posted June 7, 2005 Share Posted June 7, 2005 The NGK equivelents are; BKRE7IX's are the Iridium I think...I've got some in at the moment and they run my single. BCPR7ES' gapped to about 0.7-9 on your setup are the cheaper copper options. Link to comment Share on other sites More sharing options...
V Posted June 7, 2005 Share Posted June 7, 2005 Cheers Alex, Any pros & cons between makes? Are the BKRE7IX's Iridium ones suited for my setup? or are there other ones better suited that are Iridium? I dont fancy copper! Thanks SV Link to comment Share on other sites More sharing options...
terribleturner Posted June 7, 2005 Share Posted June 7, 2005 Funy you should say that ALex. The car has been fine ideling, but lately i noticed that im hesitating when flooring it, so im replacing the plugs. Where can i get IK24's from at a good price??

Alex Posted June 8, 2005 Share Posted June 8, 2005 V, PANKS supplied mine and yes they will suit you (eqiv. of an IK24) James, IK24's are available from your local PARTCO - but may have to be ordered in specially. I'm writing an FAQ so I can just direct you all in future Link to comment Share on other sites More sharing options...
V Posted June 9, 2005 Share Posted June 9, 2005 Just an update FYI: NGK BKR7EIX: PARTCO £5.61 each + VAT box of 4’s only PANKS £ 5.84 each + VAT MOTORSPARES £7.30 each + VAT Link to comment Share on other sites More sharing options...
Alex Posted June 10, 2005 Share Posted June 10, 2005 Think I'm running the 8EIX's at the moment...they seem to do the job but are new to the market. And yeah - I've got 2 spares as well cause of the box of 4 thing Link to comment Share on other sites More sharing options...
Gamer Posted June 10, 2005 Share Posted June 10, 2005 I ran the 8EIX's for 1 year, seemed ok on the stockers but once i went to the single and 1.5bar I had a mis on the top end. Replaced them with some IK27's and she's happy again. Link to comment Share on other sites More sharing options...
Alex Posted June 10, 2005 Share Posted June 10, 2005 Thanks for the input Gamer...I'll add it to the FAQ Link to comment Share on other sites More sharing options...
