    I installed these on my 2007 PT cruiser, and I couldn't be happier. My car is the non-turbo, but after installing these I get a great boost on acceleration. Any concerns about the heat increase being a stronger plug, don't worry. Installation was at the beginning of the Arizona summer, and driving around in 115 degrees of heat I didn't notice any changes to my cooling needs. Some reviews have issues with these plugs just being plain junk, but I disagree, if you have a performance vehicle then I recommend a professional racing plug, but for a OEM upgrade that you won't be disappointed with these are definitely worth the investment.

    I'd previously used this type of +4 plugs successfully in my 1997 XJ6, so when my 2003 Chrysler van was at the 100k service interval I chose to installed these innovative plugs. However, after installation, the van ran very poorly. I called Bosch and they advised that while their plugs are factory tested for compatibility, as any vehicle ages, there's a chance that due to wear characteristics, non-oem plugs may cease to be fully compatible. They suggested that I return the plugs under their satisfaction policy. Upon reviewing on-line blogs, I also discovered a frequency of citations of incompatibility between the +4 plugs and the Chrysler vans. I chose to accept the manufacturer's advice and went through the trouble of removing the Bosch plugs and replacing them with Champion Double Platinum plugs. For my trouble I realized a net cost savings and have the van running well again. [...] As I implied above, I'd previously had a great experience with these +4 plugs, but after my most recent experience with my van I'd advise that before selecting the +4 you Google for any incompatibility postings for your vehicle. The bottom line is that while the +4 have been terrific in one car they were terrible in the other.

                Got these because they were on sale and were cheaper than ac delco iridium. replacement was a breeze on my 07 HHR. gas mileage on 100k mile plugs was 26-27 mpg and after the change we are back to 30-32 mpg depending on driving conditions. i wouldnt say they improve power or mileage over stock plugs...but a definite improvement over the 100k mile plugs i replaced.

                            The heat range number located on the insulator indicates the temperature range of each spark plug. The lower the number, the hotter the plug; the higher the number, the colder the plug.
