NGK Iridium Spark Plugs SET of four, 08-09 Caliber SRT-4
Model Number: 221263
These spark plugs are the most popular, and best spark plug available for the 08-09 Caliber SRT-4.
If you have over 25-30,000 miles on your spark plugs, or if you have increased the boost on your Caliber SRT-4, then its time to change your spark plugs.
NGK Iridium plugs are the BEST plug we have ever tested in turbocharged cars. These plugs improve acceleration, eliminate stumbling under boost, create a smoother idle over worn plugs, and can withstand high temperatures from turbo engines.
These spark plugs come with a gap of .035-.038 thousandths, however, the recommended gap is .032, so the gap on these plugs must be checked/reduced before being installed.
