Taking out the spacer isnt going to improve power but I wouldnt even run one, dont they make a whistling noise??
And I mean getting more POWER is not easily achieved without spending a lot of money. And if your towing, what do you need so much extra power for? are you going to be racing on the freeway with your family in the car? lol... I mean my 05 5.4 only upgrade is a K&N Intake and I tow fine!
If anything just get the gryphon with custom tunes to benefit the CAI and overall performance...
