What are some good mods not yet included in the 65+ Efficiency Mods?

I'll edit this post and add them as they're mentioned.

Good mods should be added to the then 66+ mods list.

I'd say HID and LED light conversion.

A litre of gas has an energetic value equivalent of 8.87 kWh, but by the time the engine has converted it into rotation power and the alternator converted that into electricity, only some 15% (1.25 kWh or such) is usable for electric appliances.

Changing the 55W headlights to 35W HIDs, 55W front foglights to 7.5W LEDs, 5W parking ligts and license plates lights etc. can save you 60 W or more depending on the lighting situation. That will save you a litre of fuel in every 15 hours iof driving. And it gets you more light (HID vs halogen) and a 0.1 % performance enhancement.

This is the conversion I'm about to execute right now.

Thanks, guys.

I know I have let a few go ignored that should be on the list. I'll add 'em after others chime in.

Cross-checking against the wiki is probably the best idea - Weather Spotter & other wiki contributors have been keeping that more up to date.

Megasquirt! I'm surprised it's not already listed.
(or any programmable efi)

I think there is about 80 mods on the wiki now.
