Ngk Spark Plugs


New Member
Im looking to get some opinions on spark plugs, I have been using autolite plugs for a long time and I might give NGK plugs a try but I want to see if anyone has any thoughts on the NGKs and if they are even worth it or even if there are any performance gains. .. I also notice a new plug called E3, They are alittle pricey..

I would appreciate any opinions...

NGK here too!

Made the mistake of putting NGK UR5's in my GN1's Wow! no kidding Short plugs! Almost HALF of the threads inside the heads were unused and was giving me a lousey burn! Thanks to comments from here, went to longer TR5's from UR's and the car roasts its tires again shifting gears! Advanced Auto had them for only $1.87 ea.
