dandan Posted August 12, 2003 Share Posted August 12, 2003 Hi all, I'm looking to replace my plugs asap but am stuck as to the best type. I've searched all past posts but got no real feel for the best plug for my spec. I believe one of the NGK types is suitable but not sure exact one. Don't really want to shell out megabucks for HKS so can anyone recommend a plug, with rough cost and supplier please. 58,000 mile T Turbo Steel turbine jap turbos 2nd cat out (first to follow very soon) Trial exhaust Apexi BOV DSBC Running from 1.00 - 1.15 bar of boost Any suggestions much appreciated.

Geezabloke Posted August 12, 2003 Share Posted August 12, 2003 Im currently using the NGK's upto 1.2 bar boost with no probs.........:flame Dev Quote Link to comment Share on other sites More sharing options...
Thorin Posted August 12, 2003 Share Posted August 12, 2003 Denso's are my preference. Quote Link to comment Share on other sites More sharing options...
dandan Posted August 12, 2003 Author Share Posted August 12, 2003 As the car is coming up to it's 60,000 mile service in the next couple of months i may just go for the NGK's for now and see how it goes. If there are any problems i'll swap them at the service. Are these the only two decent plugs to use without going into silly money? Any idea where i can get the NGK's from and what i need to gap them to? Quote Link to comment Share on other sites More sharing options...

Justin Posted August 13, 2003 Share Posted August 13, 2003 When I decatted fully my engine started spluttering so needed cooler plugs. I fitted NGK Laser Platinum PFR7B - 4853 from Chris Wilson and they did the trick perfectly. Not cheap though! Quote Link to comment Share on other sites More sharing options...

dandan Posted August 14, 2003 Author Share Posted August 14, 2003 cw suggested those plugs to me i think when i have my service (and probably the first cat out to) he said about £100 a set! regarding cats can you check out this thread and give me your opinions please????? http://www.mkivsupra.net/vbb/showthread.php?s=&threadid=11125 cheers all Quote Link to comment Share on other sites More sharing options...
eyefi Posted August 14, 2003 Share Posted August 14, 2003 dan, what else do u want answering in that cat thread? Quote Link to comment Share on other sites More sharing options...
dandan Posted August 14, 2003 Author Share Posted August 14, 2003 Thanks for looking eyefi, I don't need to get rid of the cat in order to raise the boost as i have a dsbc. I really wanted to know if it was something worth doing performance wise. Most people seem to do it to gain a boost increase. Am i likely to get lower egt's and less hot exhaust gas lurking around combustion chamber after combustion, basically is it a sound step forward as far as modifications go. (i'd like some benefit to offset possible mot trouble) Quote Link to comment Share on other sites More sharing options...

But a DSBC cannot lower boost only raise it Quote Link to comment Share on other sites More sharing options...
eyefi Posted August 14, 2003 Share Posted August 14, 2003 i think u'll get slightly lower egt's with all cats out. the engine bay may b a degree or 2 cooler. to be honest i dont think theres much in it, except noise Quote Link to comment Share on other sites More sharing options...

(i'd like some benefit to offset possible mot trouble) I ran at 1.2 bar (with a boost controller) with the first CAT in. Then removed the first CAT and still run at 1.2bar. My car definetely feels more responsive and quicker. IMHO running a CAT def lowers your BHP because it restricts exhaust gasses. Hope that helps.

dandan Posted August 15, 2003 Author Share Posted August 15, 2003 thanks people, thanks for your input darren are you running a uk or jap car? eyefi, i'm getting the feling from everyone that the car sounds louder and better with the cats out so at least that's one definite benefit editted: i'm obviously not with it today, just read your signature!!
