Hello all,

I'm going to take my 04 FX4 Screw 5.4 in for some PM work and was wondering did our trucks come with the double plantinum plugs or not? Are they worth the extra 50 bucks?

Is there an upgrade tranny fluid I should consider?

Is there a cabin filter on our trucks?

What would be a good tire increase on the stock rims without (18") I'm thinking just a small increase on the GY silentarmour to 285/70/18...thoughts

I plan on replacing the fuel filter myself as well as the oil changes.

Any thing else I should consider/

Thanks
Jon
