this is what happens to your plugs when you run race gas on a daily driver. btw, thats not rust. it is methycyclopentadienyl maganese tricarbonyl or MMT. it is an anti knock additive they put in race gas to replace the lead. when you run race gas and dont drive your car super hard all the time, the MMT doesnt get completely burnt and bonds to your plugs. nothing is mechanically wrong with my engine, and in theory i could keep running these plugs, but its always smart to pull your plugs every 1000 miles or so just to keep an eye on them.

 

time to replace with the spoon plugs eh?

 

why run race gas?

 

to prevent detonation. because my car runs better with it. because i can afford it. because i like supporting the mom and pop shop i buy it from for their support in motorsports. etc etc etc.....

 

hahaha those WERE the spoon plugs. but a little hint of advice to save 20 bucks. the spoon plugs are denso IK24 iridium plugs that are about two steps colder than stock. the spoon ones are exactly the same plug but about 5 bucks more a plug.

 

as with most "spoon" and "mugen" stuff haha. spoon radiator cap? no thanks

 

no. they only really do that with parts that are replaceable maintenance. i dont know about mugen.

 

Why no response...get me all excited and shit

 

why do you want to run a colder spark plug? what exactly makes the plug colder?

 

im not going to get too technical with this but in a nutshell, the colder a plug, the longer the electrode/insulator is on the tip of the spark plug. the more surface area of the electrode makes for better heat dispersion. when adding any type of forced induction to a internal combustion engine it creates more heat. the colder the plug, the wider the spectrum of operating temperature is, thus creating less chance of detonation.

 

makes sense. more metal = more heat dispersal. so would a regular l15 motor be affected by these? would it help or hinder?

 

it would help if you run your car for long periods of time or run it hard alot. just for regular city driving, they wouldnt be beneficial.

 

would it affect the performance for light city driving?

 

nah, you wouldnt feel any difference. it would run smooth when you put them in as any car will with fresh and clean plugs, but they may foul quicker over time. honda puts alot of R&D into what plugs are best for the L15 and unless you drastically change their basic design, its best not to tinker with their recommendations.

 

so i assume you would be making much more power with 104 octane?

you should be putting more down than 175whp i would think

or is your tune configured for 104?

 

yea, when i got my tune, i was running 104. the HP gains from running it are probably about 3-5 extra Hp. its more about precaution and safety for me when running that gas. i have weened my car off the 104 and now run pump gas without issue.

 

Its all good

 

see that would scare me if my car wasn't tuned for it

i've seen some bad cases of messing with octane
like when i went to get my s2k dynoed
some kid had a single jic exhaust and intake and dynoed at 187 because he ran 87 octane in his s2k
i made 220 with invidia headerback and k&n filter w/ 93

i know our motors run with semi-high compresson but it would just worry me a bit, plus i don't really know how greddy ultimate ecu's 'act'

 

wow...yeah it is always good to check esp plug no matter what owner manual says but to check it every 1K to 3K to keep an idea of how the engine is truly running..pluigs will tell u alot of info

 

how hard is it to get to the plugs and wires on the fit?
are they at the firewall side?
