🔥 Champion Spark Plug 7989 - Double Platinum Performance Review

As most F150 owners know, 2004 thru 2008 models are notorious for bad spark plugs. Luckily when I changed mine the previous owner was smart enough to use it. Didn't break anything. I love these plugs.

I chose these because they are solid. I've followed FORD's TSB to remove the OEM (took a day and a half, left the solvent for a couple of hours and two plugs overnight, didn't have a break) and I won't use them unless I'm forced to Resoldered to 45 thousandths, lubricated on the smooth part of the tip, twisted to norm and no problems.

After changing my spark plugs in my 2007 F-150 it was a nightmare whatever you do don't build these champions in within two months Her Ford a I changed all 8 blown spark plugs, never spent more money on spark plugs in my life, 4 blew and started misfiring, replaced them with the same type of plugs and paid $22 for the plugs at O'Reillys, Don .

At first they seemed great spark plugs, but after about 3 weeks I started having intermittent misfires. Eventually (over the course of about 3 days) it got so bad that the code set and engine light came on. I pulled the spark plug out of the misfiring cylinder and found that the tip of the electrode was completely gone. I pulled out another plug and found the same…

is my second set of 7989s. Shortly after I bought my truck I found out about the spark plug problem, I removed (a few broken) the original 30,000 mile spark plugs and installed a 7989 kit with TSB anti-seize compound. This week I replaced that kit with a new 7989 94k mile kit. Although the spark plugs are rated for 100,000 miles, I felt it wise to avoid problems. 7989 did its job; None broke during removal. This does not mean that they came out easily. They made a similar sound to the original…
