4.6 Performance upgrades
I have put a K&N cold air intake, dual exhaust with no mufflers, throttle body spacer, and Edge Evolution on my 98 4.6. What are some more good performance parts I can add to it ?? Iam thinking of ordering a mass air flow sensor, good or bad idea ??? Thanks you for any help..

Bad idea. Save your money! The mass air will give you 0 HP.
An electric fan will help a little. About 8 HP I think. Other then that you need to spend a lot to up your HP now. You have done most of the cheaper upgrades already.

The throttle body spacer was a waste of money. It works better as a paper weight.
Do you have headers?
Ever thought about a cam? That'll give you about 25HP and the same, if not more torque depending on the grind.
Im pretty big into ATV's, and after the "Big 3" (Exhaust, Intake, EFI programmer), your next step is internal engine mods...

I've got to agree about the spacer, mine sucked.
However, I'll add some other ideas. "Shift kits" make driving a lot of fun, I did a factory tech valve body for it's ease. Torque converters with higher stall speeds and multipliers can make it feel like there is more power. I didn't notice much when my headers went on. I am thinking very hard about doing cams and heads. I just wish there was a better choice than ported stock heads. Gears can make your truck feel lighter.

I've seen these for a 5.4L, but not a 4.6L, though they may be available. http://store.summitracing.com/partde...5&autoview=sku
