Was looking for some minor performance parts for the 3.9 non mag and quickly found nothing but I found these spacers is it worth the 25 to 30$ for it?

For the single plane intake that the 3.9L had it could help a bit. Which throttle body is on your year? Is it the one with the fuel injected directly into the TB?

87 used the Holley carb, 88-91 used a single point electronic fuel injection which is why I asked because yours could be either. If it's a carb then run the TB spacer, it'll help with the air/fuel mix before it hits the plenum.

Never mind my friend has a 89 dakota sport with the 3.9 he confirmed that it has the fuel injected tb so is it worth it?

It's still injected before it enters the plenum, a throttle body spacer is a worthwhile investment.
