I just bumped up my Mini from the 200 HP JCW kit to the 210 kit with a JCW Motorsport CAT Pipe and Manifold to increase my HP to 220. One of the things that came in the JCW 210 kit was the JCW Airfilter, which is described as:

"The unforgettably throaty sound of the engine will register instantly in your ears.
There is a second air intake controlled by means of an electronically actuated flap, which opens during acceleration at 4 500 rpm. The result is a significantly improved performance curve and an even more distinctive sound."

I had a DINAN Cold Air Intake on my MCS before installing all of my latest upgrades, which is Always Open.

So the question I'm posing to everyone is, does anyone know which Airfilter is better; the JCW which opens a second air intake at around 4500 rpm or the DINAN Cold Air intake which is always open???

Many thanks!

By the way, if anyone is interested in maxing out your Mini with the JCW, talk to Paul Cooper of JCW, he was extremely helpful.

you have 220 bhp and you think its the fastest around...

I guess the guys over there in the States running over 300bhp would have something to say about that...

There is a thought that the JCW airbox denies you bhp below 4500 revs, hp that you have paid to obtain., However, most JCW owners really like the distinct '2 phase' approach the JCW box gives you....

My car is in for a JCW kit now. The main advantage of the JCW intake over others is less noise below 4500 rpm. Some feel it may offer less power below 4500 rpm because of that. I think that's probably right if you have a highly tuned engine that needs more air below 4500, like a 19% pulley and possibly what you have with your JCW header and CAT but probably not unless you go to at least 17%.. ITG makes a replacement filter that probably flows better than the JCW and I think there are some others out there that could be easily fitted. Installation instructions for the JCW kit call for plugging the lower hole in the back wall of the air box. It has been suggested that you may not want to do that, so you can continue to get more air below 4500. Just put back or leave in the original little bellows connection. This will probably result in just slightly more noise. I think with an unpluged lower hole and a better flowing filter the JCW intake will be one of the best and still quieter, than the rest.

I am very interested in knowing what it cost to get the JCW header and CAT pipe to the U.S.A.

I'm not sure why you would care about bhp below 4500 RPM. The torque that the engine produces would seem to be a much more important determinant of vehicle performance at these engine speeds. I've wondered if less really is more where intake restriction is concerned. Would a car with TOO free-flowing an intake suffer the same drivability issues that would affect an older over-carbed engine? Does the presence of a supercharger make this a non-issue with the MCS? No answers here, just food for thought.

Also, maybe I missed something, but I did not see where the original poster suggested that his MINI was the fastest around.

Perhaps you should re-read my post, paying particular attention to his quoted first post, which I see has been editted.

Beat me to it... a worthwhile hint to any forum reader joining a contentious topic late!

Missed the edit. Makes much more sense now.

Thanks for the information guys and gals. I think I'm going to stay with the DINAN based on your feedback. However, the idea of removing the plug in the JCW airbox is a good recommendation.

Ok, so I am jumping in late

Is the JCW box best bang for the buck? And adding a cold air intake going to void the warranty?

Thanks

The JCW Intake lists for $475 but Helix Minisports sells it for $250.

At $135 from OutMotoring, the Pilo Intake offers the "best bang for the buck".

The JCW Intake will be covered by warranty if installed by a dealer. An aftermarket intake will not void a warranty unless it is identified as the cause of a problem.
