Iridium Plugs

[luvmypt]

Has anyone tried the Denso Iridium plugs on their PT. I am looking to redue my plug and wires and perhaps coil. I have read of some increased performance with double platinum plugs but here that Iridium is even better. What do you all think.

[Sci-Fi]

The Denso Iridium Spark Plugs are NOT designed for the PT. Plus you need to use a custom made spark wire set and a "special spark plug socket" in order to install and remove them. Do a search and you will find out the differences between the Denso and the stock spark plugs. Then you can decide whether or not you want to go with Denso's. Believe JeffB mentioned Neon 2.0L spark plug wires "MAY" work, but that doesn't solve the problem of having to use a lathed down spark plug socket that may crack or get lost. http://ptenthusiasts.org/PTForums/sh...=denso+iridium

IMHO, if you gap the Champion Double Platinum's or regular Champion spark plugs at .040 (the same gap that is standard on the Iridiums), you should see the same performance. Also, you can use any of the current OEM or aftermarket spark plug wires (Crane, Magnecore, LiveWires, Taylor, etc.) listed for your PT.

MY OPINION:
The newer ignition systems put out all the spark you need when new. The plugs and wires are replacement items - I got the Champion platinums and Crane wires expecting them to last longer - and they are already past the stock stuff's lifetime (I have close to 75,000 miles on my PT).
As to Irridium plugs - HYPE.
The only way you'll see a performance benefit is if your current parts are below par and you restore spark to where it oughta be.
The above is MY OPINION.

Like QSD said, a lot of hype.
I just purchased a set of Mopar performance wires (7.5mm spiral core) and they are marked 500 ohms/foot resistance. The short ones actually measured 309-311 ohms and the long ones are 384 ohms. The specs on the OEM wires call for a range of 2360-7070 ohms for the short and 2970-8910 ohms for the long ones. As you can see by the numbers, the performance wires should last a lot longer before they "ware" to the point that they would cause a misfiring problem. I am also installing the Champion double Platinum plugs, #7570, gapped at .040-.043 again for longevity.

Thanks for the input guys. I am going with the Champion double platinums and a set of Livewire wires. Lets see how that does and maybe add the Screamin Demon Coil later. Thanks again.

Buy the screamin demon coil directly from Performance Distributors in Memphis, TN. 901-396-5782 ask for Brian. Outstanding customer service as well as excellent pricing. Performance Distributors are the actual manufacturers of the Screamin Demon coil. Brian will not only get your part out, but if something ever were to go wrong, he, and the company, will do everything in their power to make you happy. I am a VERY SATISFIED customer. You can even mention my name to them.
Enjoy,

Monarch products makes a specially designed set of plug wires so that the iridium plugs can be installed. For around $100 total cost, this is the best performance enhancement you can make to your PT. Increased HP, increased fuel efficiency for that kind of money, you can't beat it. go to http://www.sparkplugs.com. Read next quarters Cruiser Quarterly for another fellows opinion who made the same mod.

To be honest I rather doubt a coil or plug change will do anything for a PT Cruiser if the original coil/plugs are working properly. Need to put in a whole new performance ignition system if you want to upgrade and do any good and then only for WOT stuff!

I've looked around and figured it was worth a shot. Mine are coming in this week.
