Review on 🔥 High-Performance MAS Ignition Coils DG511 GD511 FD508 + Motorcraft Spark Plugs SP546 PZH14F Bundle - Compatible with Ford Lincoln F150 2005-2008 (8-Pack, SP515 Compatible) by Dan Sturm

Ordered there due to normal terrible shake 5.4, knew better to run coils so I just ordered them to use rubber boots. Anyway, I installed spark plugs which are supposed to be the latest design 5.4 3V to replace the SP 515 but since installing them my truck has not even been able to pull out of the driveway. I replaced the spark plugs with a cheap Autolite to see if they were spark plugs after changing 2 sets of coils and all but 1 of the spark plugs were bad. The top that snaps into the spring on the coils is .10" shorter and thicker, which prevents contact. bad right after a few days i figured it out and fixed my truck with brand new parts.very disappointing wasted my money.
