Default Spark plug socket size and torque setting on plugs

What size socket should I have for the plugs?

5/8" deepwell or 15mm will do it.

The PT plugs are the thin type. I believe 5/8". They sell special plug sockets for these thin plugs that have a rubber insert to hold the plug steady and probably help you not break off the tip.

I bought the deep well 5/8" last night but without the rubber insert.

Now I need to know how to read the torque ratchet and what torque for the plugs.
I heard it needs to be torqued at 13ft lbs?

Not sure of the torque required but the wrench should be easy to read. Should be a gauge on the tool, just tighten it until the gauge or needle reads the correct torque and thats it.

If it is 13ft/lbs thats not much, go easy on that wrench young man!!

Don't know if all torque wrenches are the same but most have at least 2 different types of measurements ie: foot pounds / KPS-KGS. The tip/bottom of the wrench tightens or holds the setting, unloosen that first, then start turning the handle until the handle top is level with the marked indicator on the bar at 13 foot pounds. Tighten down the tip of the bar to lock in the setting. At least that's how mine works. [:I] 13 foot pounds is not much, don't over do it and make sure you use Anti-Seize Lubricant on the plug threads.

Wow! Nice PT. I have had mine for 18months(2001)(139,530miles). I do all my oil changes. Getting set to tune-up. Plan on Bosch platinum+4 plugs, Autolite Professional plug wires, and Accel Super ignition coil. I have heard that changing the coil may not be necessary. Is this true?

Yes.
Stock coil is fine.
Are the Bosch plugs the ones with 4 side electrodes and a center post?
Why do you think those are a good idea? Spark will only jump from one outside electrode to the center - whichever one is shortest gap - and I don't know how you would gap them.

This is off topic of this thread... but

The aftermarket transformers (coil pack) are better quality then the stock OEM coil. However the output is the same comparing them to an OEM..
The ACCEL (yellow) is exactly the same as the MSD(RED) so they definitely bring the "bling" factor for under hood decoration. I personally prefer the MSD.
I would say that on oscilloscope evaluation both of these did better overall then a stock coil but that was mainly because of the conductivity of the material used.

Most any spark plug you choose will do just fine. The only real way to find the optimum spark plug and gap is through testing.

I recommend to read the spark plug recommendation for any installation and torque setting. They could be very different then the service manual values. i.e. Champion say to tighten to 1/16 turn from snug. Or at least get the specific torque value and contact the spark plug you choose technical information department and ask them. Incorrectly installing spark plugs is the number one cause of damage to the threads in a head. Also if you over torque a spark plug you could unknowingly crack the insulator which may not be apparent in the running condition of the engine at first.

Most muti ground electrodes do not require gaping form their packaging. Refer to the manufacture of the spark plug for this information only. NOT a service manual.

That makes some sense although plug directions may not take into account an aluminum head.

FWIW, the 08 manual for the 2.4L NA does say 13'# (17.5N-m).

With this Warning in bold: The tapered seat plugs for this application are torque-critical! It is imperative that 13'# is NOT exceeded! (Same for Turbo.)
