Ramair Filters SR-225-BL-ECU Performance Induction Kit with Ecu Relocation Bracket and Silicone Hoses, Blue

OK, so first of all I got a lot of responsiveness and better acceleration from fitting this part. I have a 3" exhaust, stage 2 intercooler and a stage 2 map. And this mod gave my car a considerable boost.Now for a little advice.The air box is the most difficult part to remove, but if you take off the MAF and the down pipe for the air scoop it'll come out a lot easier. You need to move the box to the right and then tilt it up to get it out easier. This video helped "Focus XR5 Turbo / ST225 airbox removal" search for it on YouTube.Next I used "#13 How to install a Air Inductuion Kit on a Ford Focus ST Mk2" again a YouTube video that will give you a good idea how to do the job properly.I'm mechanically minded but don't have any experience doing this sort of work and I managed to do it in the freezing cold with just a few basic tools.I'd highly recommend doing this job if you're inclined. The sound is awesome and you get a nice boost in power from it.Good luck.

Brilliant product. Easy to install if you know how too. Either way it comes with a step by step installation manual with pictures ,sounds amazing and got delivered next day. Highly recommended cheers guys 😊

Couldn't be happier with my purchase... Easy to follow instructions for install

This product comes with the wrong size bolts to fit the ecu which is no good when you fit it on a sunday and your car is off thecroad as you cannot get the right fitting bolts with no shops open.

Sounds great

Amazing sound crisper acceleration. An looks good.was supposed to come with a free gift wich never came

Great filter and easy to install but the 3 bolts for the ECU mount were the wrong size so I had to go out (in a taxi as my car had no air filter on) and purchase replacement bolts... annoying and an extra cost I didn't want.

Very happy with this
