bodilx6 Posted March 5, 2009 Share Posted March 5, 2009 they are gapped to 0.4mm. Can that be right for BPU level 1.2bar as it says in the technical FAQ? All other plugs mentioned for BPU are gapped at 0.7mm but Denso might be different in temp, or? Quote Link to comment Share on other sites More sharing options...
Homer Posted March 5, 2009 Share Posted March 5, 2009 You don't gap iridium plugs, just leave them as they come. The gapping is only needed for other 'traditional' plugs Quote Link to comment Share on other sites More sharing options...
bodilx6 Posted March 5, 2009 Author Share Posted March 5, 2009 yeah, but it has a set gap of 0,4mm. I thought a BPU supra needed 0,7mm. i remember running toyota recommended platinum set at 0.5mm which resultet in misfire. but after gapping them to 0.7mm (as the FAQ states are used with most BPU recommended plugs) all was well. Can it be that IK22 are correct for a 1.2bar BPU @0.4mm due to some other variable? Quote Link to comment Share on other sites More sharing options...
hadyn Posted March 5, 2009 Share Posted March 5, 2009 Dont manually gap iridium plugs as this can knacker the tips... Quote Link to comment Share on other sites More sharing options...
bodilx6 Posted March 5, 2009 Author Share Posted March 5, 2009 nono, I'm not gonna do that. I just need to know if my IK22 really are the right ones even though they are @ 0.4mm compared to 0.7 for most others recommended for BPU Quote Link to comment Share on other sites More sharing options...
Homer Posted March 5, 2009 Share Posted March 5, 2009 At the risk of repeating whats been said - you don't gap iridium plugs The gaps only apply to the likes of copper plugs. Iridiums should be left alone. If they are IK22's thats all you need to know, just fit them and forget about gaps Quote Link to comment Share on other sites More sharing options...
bodilx6 Posted March 5, 2009 Author Share Posted March 5, 2009 Thanks, thats what I needed to know. I got unsure of the IK22's when I saw they were 0.4mm and most others were 0.7mm. I know they arent to be gapped manually, but you can see my concern when their specifications er very different than the other reccomended. How come they work with 0.4mm gap when others are 0.7mm at same boost/tune level? Quote Link to comment Share on other sites More sharing options...
Alex Posted March 5, 2009 Share Posted March 5, 2009 LOL - 0.4mm is the ELECTRODE size! Not the gap! Quote Link to comment Share on other sites More sharing options...

Alex Posted March 6, 2009 Share Posted March 6, 2009 Get a set of feeler (sp) gauges and check. No don't, this can damage the electrode. You don't need to if they are fresh out of a new box. Quote Link to comment Share on other sites More sharing options...
