VXR spark plugs?
I know the stock plugs are the ngk lfr6a but has anyone used the ngk lfr6a-11 v tip plugs that use less electrical but has better performance and gas mileage? Its only a 50 cent difference but if it's better I would like to get them.
I know some are sceptical on different plugs doing anything at all but I feel that sometimes different ones do work better.

I have been using the v groove plugs since day one because they didn't offer an iridium plug. I ck them regularly and they stay very clean.

I figured out the difference. It's not much just the spark gap. But I found the iridium equivalent.

I use iridiums in everything else I have . Really clean burn. No wasted fuel. IMO

Here is what ngks website shows. I found a cool sheet to show what everything means.

I bought the ones with the swirlie they swirl the spark right on top the piston for extra horsepower

The 11 is 1.1mm gap..that is not the recommended gap for Yamaha banging down gap is not ideal......you need the ones with out the 11 and there are only two spots I have found and both are overseas......I run Iridium plugs they came the proper gap.....I bought them from eBay and there INT plugs

Its .8-.9 mm so 2 off to adjust isn't that bad. Also my plugs at stock were at 1.0 ±mm
