Hey guys,

How are all ya doing? So this weekend im going to change the spark plugs on my 2004 v6 mustang for the 1st time, so I want to know is the NGK TR55IX IX Iridium Spark Plugs a good choice for the v6s?

Thanks

My mods are: K&N RAI, BBK 65mm throttle, O/R H pipe, dual catback and with a 91 racing tune

No need to spend that kind of money.
Sure they are good plugs, but you wont gain anything out of them but lighter pockets.

The NGK Plats are very good and fairly cheap.
I run them in everything and am very happy.

I had a set, got them for free from an old sponsor on here. They did nothing. I run TR-6's now. I'd recommend TR-5's for moderately modded 6'ers.

Stick with a tr6 ~
