Jack 546 Posted January 5, 2017 Report Share Posted January 5, 2017 Finally, just to add some more info and thoroughly beat this horse senseless …... I also made a call to NGK USA headquarters and talked to a tech who after looking up NGK ILFR7B8, told me that if I want a plug with the identical specs (as to heat range, gap, projection, etc.) and that is readily available , I can go with NGK's LFR7AIX plug. The only difference is that the "IX" series plugs do not use a platinum tip on the ground, hence the shorter recommended life span of 40-50K miles. By way of comparison, NGK's representation for the "Laser Iridium" series (stock) plug life span is 80-100K miles, as it uses platinum as well as iridium. I know …..

MartynB 244 Posted January 5, 2017 Report Share Posted January 5, 2017 Much appreciated Dave Yes, that style of tool is fine, I was thinking of the coin style, like this... https://www.amazon.co.uk/Silverline-202148-0-5-2-55-0-02-0-1-Inches/dp/B00865SXQ4 ...but it's horses for courses. The coin ones spread the load over more of the ground electrode and shove less metal into the nose area, so give me a slightly warmer feeling. I reckon you'll be fine, as not everyone is cool with gapping their own plugs, as you say it's a technical job and not everyone is technical. Quote Link to post Share on other sites
alias23 1,517 Posted July 28, 2018 Report Share Posted July 28, 2018 Anyone know if these would work? Track Group have them down for the V6? http://www.track-group.com/product/hks-super-fire-spark-plugs-m45il/ Lotus on back order FFS! Quote www.alias23.com Link to post Share on other sites
Jack 546 Posted July 28, 2018 Report Share Posted July 28, 2018 NGK also makes a racing plug that will work.....R7438-8 (same heat range as stock, I believe) or 1 step colder....R7438-9. Lotus supplies the latter in their GT4 Evoras. Monkeywrench has these ....... https://www.monkeywrenchracing.com/product/ngk-spark-plug-1-2gr-fe-1-step-colder-iridium/ Quote Jack2008 2-Eleven2015 Exige V6 CupR Track videos ... http://www.youtube.com/jackcup2010 Lotus Challenge Series ULTRA Class champion2012 Lotus CUP USA OPEN Class champion Link to post Share on other sites
alias23 1,517 Posted July 28, 2018 Report Share Posted July 28, 2018 I'm so confused by spark plugs! None of this makes any sense to me to be very honest! Quote www.alias23.com Link to post Share on other sites
alias23 1,517 Posted July 28, 2018 Report Share Posted July 28, 2018 Forgive me if already spelt out in this thread and I haven't been able to uncover it... but what is the exact spec of the Lotus ones? These HKS ones have the following spec and trying to understand if a good option if we find Lotus continue to be on back order!

As per the earlier comments in this thread... folks can not source the NGK specific spark plug at the specific specification recommended here in the UK. It appears to be an exclusive to Lotus hence the HKS question to understand how different it is from the lotus spec given it’s recommended by a lotus team.
