hey there, i have an 07 f-150 4.6 litre, coming up to 70,000 kms on it and its about time to change the plugs, im noticing a decrease in throttle response. Can anybody point me in the right direction on what kind of plugs would be best? or if there is any other inexpensive ways to increase my throttle response? thank you

cheers, ryan

 

We'v always used Motorcraft or Autolite. Bosch is always a problem. You could try cleaning the MAF with MAF cleaner.

 

I would just go with the Motorcraft plugs. Simply, because it seems like so many manufactures have "special" requirements for their vehicles nowadays.
