any silver / aluminium 2l throttle bodt from a mondeo should do, i think its the later ones that have a flat section milled onto the butterfly spindle (helps let even more air in!) as i have done one of these for someone, mine has a normal round spindle
quite hard to find in a scrapyard...always been removed within days of the car getting there so its def a good upgrade!
i have a waiting list for any i find!
it improves throttle response, allows the air in faster and smoother....exactly the same principle behind a proper (performance not noise!) exhaust.....basically it makes the car accelerate faster!
have a read through the comments...everyone seems happy with them
only 'bad' comment is regards to setup...the car will automatically adjust ecu within parameters but more air in means the ecu will match with the correct amount of fuel....so you will get more power...but it will cost you a little more fuel.
to put that into perspective though i can still do 32-34mpg in an frp with a lot of air flow mods with 170k miles....alll depends how heavy your foot is.
