Just swapped out the spark plugs in my Chevy HHR 2.4L, and wow, what a difference! The engine’s running smoother than ever, and I can already feel the power. If you haven’t checked yours in a while, it’s definitely worth it. Your ride will thank you! Here  is a How-To HHR YouTube video on spark plug replacement .

This 2006 Chevy HHR has over 300000 miles on the speedometer and I thought it just may be time to change the HHRs spark plugs. I have no records on this HHR so I just had to check to see if I could get lucky and find the plugs were newish. 

They came out with a bit of difficulty so I took my time and all of the plug threads looked very good.  Unfortunately the plugs showed no signs of being new.  Therefore I did the right thing in replacing them.

This was not a difficult repair. It was a bit time consuming as I took my time to discover the engine a bit more by doing this HHR spark plug replacement.  The  results were GREAT!
