compuvision02 Posted July 23, 2007 Share Posted July 23, 2007 As I stated in another thread, I know a lot about cars, but there are some things I never learned. I either didn't learn, because I had no interest or no reason. I usually learn the new things when I come across the need to do it to my car. Anyways, I am interested in getting some better spark plugs. I never needed to upgrade spark plugs, until now; I hear when you get to a certain compression level, high, it is a good idea to upgrade your plugs. Anyways, I was browsing through the inventory at work and saw that the most expensive plugs for my motor is the NGK double platinum or NGK iridium platinum plugs. I believe neither of them are supposed to be gapped, atleast the iridium platinums say that they are unadjustable. Anyways, I was wondering if either of these plugs were decent and worth the $10 a piece price tag. The double platinum plugs are gapped to 0.052" and the iridium platinum plug is gapped at a 0.044" gap, stock gap is 0.052". Link to comment Share on other sites More sharing options...
quake Posted July 23, 2007 Share Posted July 23, 2007 I have NGK Iridium plugs in my 96 civic and they seem to make my engine run a lot smoother and not to mention cleaner than my other plugs.......the .044 gap is still within the accepted gap range......

compuvision02 Posted July 23, 2007 Author Share Posted July 23, 2007 So you literally just bought them and put them in, nothing to it? I may have to buy them next pay check. Link to comment Share on other sites More sharing options...
EH6TunerDaniel Posted July 23, 2007 Share Posted July 23, 2007 Arent you going to be boosting? I would go to a colder plug. Link to comment Share on other sites More sharing options...
compuvision02 Posted July 23, 2007 Author Share Posted July 23, 2007 I'm talking for high compression. What types of plugs should you use for forced induction? I know you need colder plugs, but I don't know what the real difference is. Link to comment Share on other sites More sharing options...
quake Posted July 23, 2007 Share Posted July 23, 2007 Yeah....they went right from the box and into my engine........but as for forced induction......i'm not really sure. Link to comment Share on other sites More sharing options...
eg9-civic Posted July 23, 2007 Share Posted July 23, 2007 stick em in the freezer Link to comment Share on other sites More sharing options...
Kelkou Posted July 23, 2007 Share Posted July 23, 2007 lol. NICE eg9. lol. I put some NGK plugs in my civic when it was running, ran great, i was satisified. Plugs are the easiest change you will ever do. just take em out, put the new ones in, and you're good to go. Link to comment Share on other sites More sharing options...
TS John Posted July 23, 2007 Share Posted July 23, 2007 I think it's platinums in general that you don't gap. Plus they last longer. Iridiums are for performance, but if you can get platinum iridiums then why not? I had platinums before on my last sol and yeah, they came in the box with an acceptable gap so I just threw them in.

compuvision02 Posted July 23, 2007 Author Share Posted July 23, 2007 I know changing plugs is easy, haha. I just wanted to make sure our computers were right saying they do not need gapped. Any information on plugs for forced induction? Link to comment Share on other sites More sharing options...
TS John Posted July 23, 2007 Share Posted July 23, 2007 http://www.ngksparkplugs.com/techinfo/spar...&country=US Since you wanna keep FI engines cooler you want "cooler" spark plugs that have less exposed surface area on the plug's tip.

compuvision02 Posted July 24, 2007 Author Share Posted July 24, 2007 I actually meant to say Bosch plugs are the ones that are iridium platinums. Link to comment Share on other sites More sharing options...
TS John Posted July 24, 2007 Share Posted July 24, 2007 Stay away from Boschs. I had their platinums and they sucked. Felt like I lost response over my old-ass NGKs. Link to comment Share on other sites More sharing options...
JapaneseDomesticMarketGSR Posted July 24, 2007 Share Posted July 24, 2007 Stay away from Boschs. I had their platinums and they sucked. Felt like I lost response over my old-ass NGKs. I will second that. Complete failure in less than three months. Filament was completely blown away. Bosch plat 4=junk Link to comment Share on other sites More sharing options...
89crxsi1003 Posted August 16, 2007 Share Posted August 16, 2007 well that kindda sucks to hear i just put bosch plat 4s in my b16 in my rex damnit Link to comment Share on other sites More sharing options...
Blown330 Posted August 16, 2007 Share Posted August 16, 2007 If you are going to run plugs for performance then just get a set of NGK copper plugs. All the platinum/irridium/adamantium plugs are good for long service life but not so great for high performance/power adder engines. Irridium plugs are at best a compromise between performance and longevity but if you plan on running a higher output ignition system (MSD, etc.) then you are doing yourself no favors by running them (and paying a lot more to boot). Plus that tiny electrode that irridums use makes the spark more susceptable to spark blowout unless you close the gap down which in turn defeats the purpose of using them. I spent almost $60 on a set of NGK irridiums (TR55IX's) that proved to be worthless compared to the $2/plug copper plugs I swapped them out for.
