Iridium plugs in a 2.2

Has anybody yet upgraded to a high end Iridium plug? Any noticable improvements in driveability , performance, or mileage? Thanks!

From my experience (messing with cars since 1953) the only reason for using high end plugs in our daily drivers is the hassle of replacing them. I found on my PT that it took hours to change the plugs and did not want to do it very often so I put in plat plugs that were still working fine after 80 K when I sold the car (112 K total miles). Modern ignition systems are very very good due to the need to manage emissions. I have not looked at the HHR plug change yet but I do not think I will worry about.

Over the years I have never failed to be entertained by the ads purporting to give better performance and gas mileage by simply (fill in blank). PT Barnum was right, there is a sucker born every minute.

I just put in the Bosch IR +4 plugs in yesterday. Did it while my oil drained so it took about 30 minutes. Just take off the huge air cleaner assem and then remove each coil. Nice and easy. Use a 10 mm socket to remove the one bolt that holds down each coil.

What do you mean by "high end" iridium?? Do you mean another type/brand of iridium be? If you mean changing to an iridium plug, I believe someone on this forum indicated the plugs that are stock in the HHR ARE IRIDIUM.

2007 model yr

2008 model yr

2.2L AC 41-103, iridium tip plug

2.4L AC 41-103, iridium tip plug


Here's the AC Delco company line on the AC iridiums:

----------

The ACDelco Professional Iridium plug launches the next generation of high-performance spark plugs.

Iridium is one of the strongest, densest precious metals on earth, requiring less precious metal for the electrodes than platinum-tipped plugs, said Michelle Glazier, ACDelco product specialist for spark plugs. And with a 100,000-mile limited warranty offered by ACDelco, customers can be confident that these efficient, high performance, spark plugs are built to last.

If you look at an iridium tip, its equivalent to about the size of two pinheads, Glazier said. Its less drain on the electrical system because its smaller, and its a more efficient use of the energy in your vehicle.

Specially designed electrodes on the ACDelco Professional Iridium spark plug increase electric field strength and reduce sparking voltage, resulting in improved cold starting and quick acceleration.

A tapered, cut-ground electrode offers enhanced flame spread during combustion, while a secondary microdischarge of the center electrode burns off carbon deposits, providing superior antifouling performance.

Spark plugs are located on top of the motor (under the air filter box)..

Pic is of a 2.2 L61 (which also has a cover over the plugs)

If you don't have many miles on yours, why bother ?
