(2011-01-20 15:20:08) 1. Says: i have a 2005 F150 V8 5.4L thats all the details that matter when picking spark plugs am I correct? The fact that it is a Triton...does that make a difference in the type of sparkplugs?2. Says: The only other thing they might ask is the 8th digit of the VIN # . which will determine exactly what engine the truck has . ( because there are two different 5.4 liters ) one is a 3 valve engine and the other is a 2 valve engine .P.S. Stick with the BRAND of plugs the truck originally came with . ( in this case ford uses Motorcraft ) Also be very aware that if you have the 3 valve engine , there is a VERY , VERY special procedure for removing the plugs . They have problems with breaking off in the head and may require head removal . Not trying to scare ya , but this has been a very big issue , lawsuits and stuff . Google it and you'll see what I mean .
On the other hand , if your engine is the 2 valve , you have nothing to fear , except the fact that it's a pain in the neck to do .3. Says: Correct (as long as you haven't added forced induction). Triton is just an engine series designation nothing more.4. Says: no triton wont matter because all 2005 5.4l will be triton Tag: Sparkplug help please?
