Spark Plug Question
I was told that i should replace my spark plugs.. Trying to see what spark plugs you guys use after some performance upgrades. Someone had recommended the NGK Cold plugs i think. Ive seen a couple other ones.. I do feel a slight misfire gonna hook it up this week to Star to see if it actually is. Listed below is the info on my car. Any knowledge would be appreciated.
How often do you guys service the transmission? Normal maintenance?
06 60k
Mods are:
EC engine/trans tune
Headers
both Cat deletes
IC & Pump
Not much but rather be on the safe side.

Plugs = NGK LFR7AIX Iridium IX Spark Plugs (if you plan to increase boost in the future) or else NGK ILFR6A
Tranmission and rear diff service should be done. make sure you change the eletrical connector on the transmission this will prevent the fluid from wicking up into your TCU over time.

Its always best evey 50-75 HP over stock to go down a heat Range in plugs. We would recommend using LFR-7AIX and we sell the set of 16 for $129.95 if you have no luck finding them.

I got the LFR7AIX plugs
prices usually fluctuate a dollar or two up or down, but if you can swing the Prime free shipping - Amazon is pretty competitive at most times...
I got my set for $113 shipped

Like Toad said Amazon is a good place to get them but right now at $9ea the total will come to $162, so Steve at FTP is a good pick for these right now.
Amazon set I last got was $7.85ea, totaling $141.

yaH I ordered mine last night too...... about to tear down the covers soon give them a fresh new coat of wrinkle paint and drop the plugs...
is there a specific tq on the plugs or just enough so they are tight
