well the bosch platinum +4's are out...they suck..make my motor run like ****..but I found some denso plugs....just basic copper ones (stock 96 civic hx)...I know denso is a good company but for a stock motor like this a cooler burning copper plug would do just fine right?....is denso preferred over ngk's (i thought they were connected somehow) in honda motors? Basically would i be better off just running basic denso copper plugs if I'm just looking to get good mpgs out of it?...thanks in advance

 

Stock spec NGKs are all you need. Those Bosch 4+ platinums were an absolute waste of money on your motor.

 

NGK all tha WAY

 

NGK > *

 

yeah they were a waste of money.....but for some reason i have it in my head that denso makes ngk...correct me if i am wrong
