My old Mercury Grand Marquis has never run better! I just replaced the original spark plugs and coils after a little over 100,000 miles and my sedan runs like new. I considered using Motorcraft plugs like the O.E ones, but have had good luck with NGK plugs in the past, so at considerable savings I bought these plugs.

I tried these plugs in my 2001 Tahoe and 2000 Camaro z28 and they did not like them at all. The both misfired and idled bad. 2 of the plugs were cracked. I took these out and put some acdelcos in and noe they run good.
