Default Proper spark plug gap for '01

I am trying to find the TSB 08-008-04, which applies to new spark plugs and their gap. I was wondering if that TSB applies to the 2001 model year. Our car has 60,000 miles and I want to change the plugs and ignition cables.
Could someone help me with this question; Do I need to set new plugs at .40 gap or stay with the old gap of .50 ?? Also should I get new plugs per the TSB (RE16MC or LZTR4A-11) or continue with a new set of old (RE14MCC5)
plugs ??
I am new to this site and just love all the great posts and info I've read so far. Weve had our PT for 8 years and love it !!!!!!!!

Welcome lukenesser to the Forum, glad to have you aboard.

Yes, the 0.40 is for the 2001 PT as well. Look at my signature for plugs (or Champion 7570), use dialetric grease and anti seize on the threads.

Welcome to the forum,

As Hooligan pointed out, what we are recommending to owners is the Champion Double Platinum plugs (7570) gapped at the new .040in They will give you at lease 50-60,000 miles of smooth running as long as you get rid of the OEM wires.

Thanks for the replies. Hooligan & Crewsin !!
The change in the gap setting from .50 to .40 has me wondering , If I haven't had any problems with my OEM plugs and wires for 60,000, why would I change to new type plugs and smaller gap ??

Doesn't a larger gap ( if properly tuned) use fuel more efficiently as long as the coil sends enough spark ??
I'm probably going with the new Champion 7570's and new premium ignition wire set.
Also is the air-raid intake worth the price for the benefits for a daily driver, 3000 miles or less a year ??

Thanks again, Ken

Glad you haven't had any problems in all those miles but many have and Chrysler came out with a TSB telling all the mechanics to change the gap to .040in to solve those problems so we advise anyone who asks to do the same.

Ask 2 people about the aftermarket air filters (Airraid) and you'll get 2 different answers. Some say it improves performance and mileage, others balk at that answer asking for proof. I for one, after adding an open filter noticed that I didn't have the "bog" that happened when I took off from a stand still. It now goes right up to red line if I care to hold down the throttle. Some say I'm loosing torque because the kind I have draws in some warmer air from the engine. I don't notice it, I also don't race from stop light to stop light. On a normal daily driver, like you say you have, i'd leave it alone and keep the filter as clean as you can. Maybe pick up a washable filter (K&N) that lasts 100,000 miles and you can clean it as often as you like to keep fresh clean air coming in.
