how too and over view on 67mm throttle body.

OK so this is a quick how too on the throttle body.
So first for tools your going to need a 8mm socket with long extension and a rachet also a t27 torx driver or bit for your rachet a flat head screw driver a pair of pliers and a smile
So in picture one your going to remove the 4 8mm bolts from the air box and the two 8mm screws from the mass air flow. Note other cars might b different sizes but those are what my car had. Then remove plug from mass air meter. Remove top of air box and pull away from mass air meter.in pic two. Now in pic three remove the clip for the throttle cable and remove cable for cruise control off of throttle body. As u can see the rubber grommet stayed on u will need to transfer that to the new throttle body also will need to transfer or replace rubber gasket and tps sensor. Then remove the 4 t27 torx screws from the throttle body. Unplug tps and remove throttle body from intake the tube and mass air meter as an assembly. The factory clamp on the intake tube for mass air meter will remain on and the one on the throttle body remove. I used the flat head screw driver at the wrinkle part of the clamp and it separated easily. Pull apart old throttle body from intake tube and pull off old clamp u will need a new hose clamp or I used a stainless zip tie for a cleaner look. Now transfer the tps and gasket plus rubber grommet to new throttle body. And install in opposite way of removing. This is a generic how too and I'm sure I might have missed thing like remove bat terminals n such but I NVR unhooked my batt n NVR had an issue. Now if u all want to add your own pics n comment to add positive stuff in the how too and such feel free I want this to help a new bee do the job on there own not to bust my rump or the next guys. Now for my opinion on the throttlebody it made a huge difference in throttle response it is very touchy. Also my car seemed to b smoother and a little more pull throughout rpm range. It also helped my car idle down faster and seem to run smoother. I am very happy with this mod and would recommend it to any one with a svt focus. Now I know people say u can get same results by porting the stock tb and my opinion is its still a 63mm inlet vs a 67mm inlet bigger holes flow more cfm which more air means more fuel which equal power. I NVR ported one but that's my opinion.

Thanx for your write up & feed back. I'd also add a tune also.

You'll feel a bit of more throttle response on, like on ramps & such. You don't need a tune for it, but its a great next mod. It is a touch bit more sensitive & takes the lazyness out of the svt linkage setup.

Exactly what Felixthecat said. I also had a dead spot at 3000 to 4500 that was cleared up also I don't have as much backfiring on decel. And it idles down faster. Throttle response is quicker and helps when taking off up a hill no more bogging.

There's no way I would have kept my 67 mm on there without my tune. It was super sensitive, maybe it was just my car. I data logged and had a new tune a couple days later. Feels so sweet now :). I also had a hard time putting the stock intake tube over the new throttle body, It was the hardest part of the job for me(anybody else have this problem?). I ended up having to lube it up a little and it still took a while, Just had to make sure it went on perfectly straight. But then I couldn't get the stock hose clamp back on either, luckily I had a spare hose clamp.

And I will get a tune eventually but the computer from the factory is smart enough to compensate air fuel for a small mod like a throttlebody
