spark plug ?

[deputylightning]

on my 02 V6 i thought of duing the sea foam diy from the thread on the boards.

saw the change of the spark plug is suggested.

i thought of going with those new tr3's but never had them in anything

any suggestion on them or is there a preffered type

The 'U Groove' sounds pretty important. Have you seen the funky tips on stock Denso pk20tr11?

I would stick with the stock Denso double tip plugs, my two cents.

I'm thinking, spark's gonna take path of lease resistance. That's probably the prong that's closest to the tip. So why bother 2 tips, does the spark really fly in 2 directions?
