I am finally going away from my K&N air filter. Only because I'm getting lazy. Don't want a K&N bashing post just help with the replacement filter. Looked at Amazon and they show a Motorcraft FA 1883 and a FA 1883B7 with the 1883B7 being priced higher. This is for my totally stock 2009 F150 with a 5.4. Does anyone know the diferance in these two filters?

 

Any bigger name air filter will do. No need to toil over a particular one. Now oil filters is a different story, motor craft is absolute.

 

The B7 costs less at Tasca Parts. Factory Direct OEM Ford, GM, Mazda, Mopar, Nissan and Volvo Parts & Accessories Online

 

The difference is that the B7 is a box of seven air filters.

 

Thank you.
