hey, i was wondering if the story behind the super 4's actually work, cause im thinkin of buying them to help out the mpg abit more, just got 412.8 miles from last fill up and wonderin if these sparks would increase it abit more as im a daily driver doin 120 mile a day
Always prefered NGK if they work in high reving multi cylinder motorcycles then they'll do for my micra, and if you're feeling rich there are always the iridium versions lol.
The NKG-r Stocks (I think) are absolutely fantastic and a very clean spark,
Im using super bosch (singles now though) and i'm finding them a bit softer then the NKG's (im certain of it) engines also louder now for some reason ?
