TB Spacer anyone?

[shooter]

Good day; Anyone know if a tb spacer is worth anything on my "03" 4.3?
I use my truck to tow a 2500lb trailer, and was thinking about one.
I need advice on this one. Thanks

I have a powerdyne spacer on my '98. It did a little and I got it free so I didn't lose anything.

The performance gains (if any) do not warrant the prices. The "helix" crap that most advertise is gimmicky and just makes a whistling noise. It barely does anything for our trucks.

I wouldn't bother with it if I were you.

Throttle body spacers only work on throttle body injected, or carbed vehicles.

Your '03 is multiport injected, so you will see no gain with one. Don't waste your money.

Use that money for something else. Power pullies and a better breathing intake would be a good start.

The only thing that a TB Spacer is good for on a 2003 is a whistle.

Waste of money as rat stated.

TBI's will see a gain just like a carb'd engine.
