Ok guys i need your quick response I'm thinking of getting the JCW airbox ( i have an 04 MCS ) my question is it worth it ? i know 5 hp isn't alot and the car opens up more at 4500 rpms when the other flap opens up > my question does it improve the driveabilty of the car in all rpm ranges ??? or is it just a waste of 475.00 dollars? and does it make the car louder at idle?
I don't have anything to compare it to since I had mine on when I picked it up and I haven't driven any other CAI's but I like it. Since mine is still in break-in I haven't broken the 4,500rpm barrier much but when I've needed to the power has been good. I also feel like it gives me more power lower (probably from the injectors that are also included). The MA that sold me the car was impressed. It was the first she'd seen with that addittion (and not the whole JCW) and said she'd have to get it for her car also. Just my 1 cent (don't have another to offer)
Its hard to tell if it adds much power (but its probably hard to tell a 5hp diff anyways). It does look OEM under the hood/bonnet which (in my opinion) a definite plus over other aftermarket intakes. Plus the sound is pretty nice once the flap opens up (and sometimes you want things quiet, when the flap is closed which is nice too) When I first put it on I found myself driving the car a little harder so I could hear the sweet whine.
Actually, there is the $450 JCW Air Filter Kit and the $560 JCW Upgrade Kit.
The latter Kit includes larger fuel injectors and an ECU remap in addition to the JCW Air Filter, and is intended to upgrade the older JCW Engine Tuning Kit to 207 hp. Something which has been poplular over on NAM is two people splitting the cost of the Upgrade Kit with one person taking the air filter and the other the larger injectors.
Does anybody know if you can buy the JCW upgrade kit from 200bhp to 210bhp for a standard cooper S from UK dealers,as mentioned in the link below. Ive just ordered a works air filter with my dealer and I have just read this topic and am wondering If its possible to buy the upgrade kit with the injectors???
