There are actually 2 of them. One is right before the throttle body, that little box coming off the intake tube. And the other is on the inlet duct under the air box. I removed the bottom one with the whole inlet duct and added a cone filter. Did not seem to be a very noticable mod to do IMO. I would not have done it if I know what I do now.sartainusn said:
