Upgrade Spark Plugs?

Hello,

Just wondering what type of spark plugs every one has upgraded to, if you have upgraded them.

I'm getting a funny business when trying to find some that are NGK, but not getting a positive feed back form people so not so sure.

What brand do you use and where did you get them from?

Thank you,

Ye, good question.. and part numbers would be great, cos this is an upcoming job for me too...

Still semi-on topic, sorry, jst ignore it if this is bothersome, don't want to be hijacking this thread, but it reminded me of a question i had in mind.

Is it worth, modifying your spark plug fitting to move the spark plug closer into the cylinder & and to the piston, or is this simply done by buying a longer spark plug, I read somewhere that this could give you a difference, because more fuel is burnt i guess...

i would say what they meant is it gives a smoother burn and a faster burn... probably doesn't burn any more fuel seeing as your cars run pretty close to perfect AF ratio's...

if you can make the A/F ignite faster and hotter you will get more power.

Mate i am with paladin on this

I strongly recommend against this as you could easily punch a hole in the top of your piston if you use the wrong size plug.

Hi,

where did you get those denso iridiums any way?

It seems like they are the ones you need to get for the mivec...

Where and how much and a part number would be great too...

And I think some one has hijacked the thread too.....

Thank you,

does anyone know if uas sells the ones for the mivec?

Or know any where else you can get these?

Thank you,
