hood pins...

[John D]

I think my Jeep gained 2 hp!

That's about 4% on a worn out 4.0L!

If I install 4 hood pins instead of 2 do I get 4hp?

I think you'll lose more weight by not eating breakfast or not wearing shoes than you will by switching to hood pins.

The real weight savings is when you scrap the steel hood in favor of a fiberglass one.
