Thanks for the input guys...

Though please be aware that only relevant abbreviations to do with cars will be added to the list.
If you are wondering why some abbreviations you mention are not added, this is the reason

[BANKS]

There’s 2 NOS

New old stock like stocky said and:

NOS: Nitrous Oxide System.

I suppose the person would be able to tell which one it is by the genre of the thread

[alien]

Oz, you forgot PCM: Powertrain Control Module!

[VKCOMMO]

dizzy = distributor

[VKCOMMO]

CI = cubic inch

[mr_vl]

NA = naturally aspirated

[VKCOMMO]

what does FML mean

[STEALTHY™]

Its a website, **** my life

[VKCOMMO]

FTW = For The Win, or F*%k The World.

i had to research that cause i didnt know what it meant

[martyna]

Thanks for the post and the abbreviation.

I think I've only ever seen an SRS system called ARS (in a book) once. It's much more commonly used abbreviation is SRS (Supplemental Restraint System), at least in this country anyway. Simply for the fact that airbags are not the only component in your restraining system. such as the seat belt pre-tensioner.

[VKCOMMO]

carb or carby - Carburetor

[wraith]

MAT = Mass Air Temperature Sensor
AFM = Air Flow Meter
HVAC = Heating, Ventilating and Airconditoning

[Timmos]

This is an excellent thread.

Thank you ozzie
