i see a lot of people asking about nitrous plugs. the ngk part number is lfr6a-11, these are great plugs... i've run them and never had a problem with them. i didn't want to wait to order them over the internet or pay the ~$6 a plug so i did some research. these plugs cross over to denso k20hr-u11 plugs, these are stock fj cruiser plugs. best part is they are only $3 a piece at your local toyota dealership and your pretty much guaranteed they'll always have them in stock. i called and they told me i better hurry up because they only have about 300 on the shelf hahaha. this is what I'm gonna start using from now on, so I'll post back if i have any problems. so far just by looking at them side by side the dimensions are exactly the same. now we have another (cheaper) option!

 

Good find. Keep us posted.

 

I get the NGK plugs from RockAuto for around $4.75 a piece but if that is a good alternative
let us know since it's something that can be picked up locally

 

will do guys, i don't foresee any problems

 

subscribed and waiting for results!

 

If you guys want to get the NGKs and save some money:

I think that's the cheapest I've found.

 

I wonder how much shipping is from there. And exchange rate.

 

Click around. I think it shows you all that. Either that or you can use a currency converter online to figure it out.

 

Yeah, I just wanted to make sure others where thinking about that before they ordered.

 

I'm just curious, where did you get your cross-over information?
