Pixelfill Posted December 15, 2006 Share Posted December 15, 2006 I've just read through Homer's BPU thread, and rather than spam the technical section thought I'd post here. I am currently running BPU but with the 2nd Cat still in, and I'm using Denso IK-24s. Now reading Homer's thread he seems to suggest that IK24s are for only singles, with IK22s being more suited for BPU. What (if any) are the drawbacks of using IK24s on a BPU engine. I have only just fitted a full set, replacing the IK24s that were already fitted when I bought the car last October, and haven't noticed any problems with the car's running.

Robert Posted December 15, 2006 Share Posted December 15, 2006 yes they are fine, i was running them on mine at BPU. Read the thread Alex wrote, the spark plug FAQ. Quote Link to comment Share on other sites More sharing options...
jamesmark Posted December 15, 2006 Share Posted December 15, 2006 Interested in this as I am also using IK24's on full BPU. And I am having problems with error code 14. Quote Link to comment Share on other sites More sharing options...
Pixelfill Posted December 15, 2006 Author Share Posted December 15, 2006 Summarising Alex's Spark Plug Faq: For boosting beyond 1 bar (up to 1.3 on a BPU TT setup) either the IK22s or the IK24s are recommended. Mike Quote Link to comment Share on other sites More sharing options...
jamesmark Posted December 15, 2006 Share Posted December 15, 2006 Whats gapping? Quote Link to comment Share on other sites More sharing options...
silvershark44 Posted December 15, 2006 Share Posted December 15, 2006 Similarly they are fine for a completely stock setup too! I have been running them for 4 months stock with no issues Quote Link to comment Share on other sites More sharing options...
Pixelfill Posted December 15, 2006 Author Share Posted December 15, 2006 Whats gapping? You shouldn't need to gap Iridium plugs, they come pre-gapped, but it refers to the distance between the electrodes at the spark plug's tip. a gap of 0.7 is 0.7 mm between the electrodes.

Mike For BPU thats too close, it should be 0.8mm. 0.7mm caused misfires on mine. edit - just realised that was an example, sorry! Quote Link to comment Share on other sites More sharing options...
jamesmark Posted December 15, 2006 Share Posted December 15, 2006 So how do you gap then? Quote Link to comment Share on other sites More sharing options...
Homer Posted December 15, 2006 Share Posted December 15, 2006 So how do you gap then? Get a set of spark plug gap gauges from your local motor factors (They're a couple of quid from halfords). Quote Link to comment Share on other sites More sharing options...
jamesmark Posted December 15, 2006 Share Posted December 15, 2006 cool and it shoudl be .8 Quote Link to comment Share on other sites More sharing options...
Jake Posted December 15, 2006 Share Posted December 15, 2006 I think you're not supposed to gap Iridium plugs because you'll damage them Quote Link to comment Share on other sites More sharing options...
Homer Posted December 15, 2006 Share Posted December 15, 2006 I think you're not supposed to gap Iridium plugs because you'll damage them Thats correct. Jamesmark, I'd assumed you're talking about gapping NGK's. Quote Link to comment Share on other sites More sharing options...
Clarkey Posted December 16, 2006 Share Posted December 16, 2006 can't remember exact part # NGK 7xx .. cost about £10 for 2 packs. (Sold in packs of 4) I used to put those in my T61 single. That was fine - and that boosted to 1.3 bar. Quote Link to comment Share on other sites More sharing options...
Jake Posted December 16, 2006 Share Posted December 16, 2006 can't remember exact part # NGK 7xx .. cost about £10 for 2 packs. (Sold in packs of 4) Do you mean BKR7E (6097)? Those and BCPR7ES (3330) are the usual NGK ones we use. Quote Link to comment Share on other sites More sharing options...

Jake Posted December 16, 2006 Share Posted December 16, 2006 That's the same ones I use in my single. Quote Link to comment Share on other sites More sharing options...
Mas Posted December 16, 2006 Share Posted December 16, 2006 Do you mean BKR7E (6097)? Those and BCPR7ES (3330) are the usual NGK ones we use. BKR7E (6097) is what Im using and to be honest for £14 a set it well worth it. Quote Link to comment Share on other sites More sharing options...
