I see a lot of people with Denso iridium spark plugs in the accord v6 site, anybody have those in there car? do those really help you a lot?

 

i just put mine in tonight. i bought them because i have NOS and have melted a spark plug before (not good). i'm using the IK20s but if you're not using forced induction (nitrous, turbo or supercharger), stick with the IK18s. The IK16 is stock plug, the 18s are a little colder and the 20 even mmore cold. if you run to cold a plug, then they will just fowl up eventually.

 

why use a 18 instead of the 16

whats the purpose of a colder plug in stockish motor

 

I think I wanna get these plugs too but which ones should I get? The 16's or the 20's? I don't plan on getting NOS or any type of forced induction just headers in the future. I want them for the gas mileage benefit. And where do I get these plugs for the best price?

 

get the 18s i you're gonna drive it hard, if not, then stick with stock (16s). i found mine at a local shop, but mmrusa.com has em for about 13 a piece

 

Holy shit, $13 a piece... thats nuts!! Anyone have the Bosch Platinum 4 plugs? I had them in my old accord and they helped a little, j/w what they might do in out cars.

 

the bosh +4 are great when you first get them
but after a while they start to suck
dont know why they just do
ive herd many people say the same thing

 

FYI fellas.. our cars cojme with stock platinum plugs if you didnt know...

also if you are looking to upgrade plugs, do not forget your wires aswell.... get an 7-10 mm (stock is 5 / 6 i believe) wire for best flow...

I have the bosch platinum plugs with magnecore racing wires (7mm)... no noticeable difference.. but its a personal satisfaction!!!

 

i hear ya on that. I have them in my car. At first i felt something..then now i dont after 20k miles. Maybe its just me. Should i get the denso iridiums???
