8 New Motorcraft Spark plugs SP509# HJFS24FP Ford Lincoln

Delivered when and as prommised.

Great product

They were there when I needed them and gaps were preset.

Packaged well, 7 out of the 8 showed up great. One had cracked porcelain. Saved an old plug to hit up the local parts store. Still way cheaper than Nap O’ Zone.

Bought these to replace in my 2009 F-150. I purchased the truck with approximately 150k miles with unknown mileage on current plugs, and replaced them at 165k miles. I don't think they were original because they didn't appear to be too rough of shape. Not related to these plugs in particular but want to mention my truck was built in October of 2008, and I had zero issues removing the old ones. I sprayed PB Blaster on the first 2, then felt like gambling and tried removing the next 2 without. Didn't notice a difference, so I continued not using PB blaster through the last 4. So if you were nervous breaking plugs in a 2009, I wouldn't worry too much. Easy job to do.

They fit perfectly, be careful though there are different spark plugs for the 08 f150. I would suggest taking one out and checking the number on them.

All right spark plugs are used and damaged. Buildup on electrode, dirty threads, and cracked ceramic. Waste of money. Don’t buy.

I gave 3 stars because I have yet to drive the vehicle and don't know how well it will do on milage. It should do well since they are new spark plugs.
