In order to maximise the airflow through the intake I've been meaning to replace the intake j-boot that fits between the throttle body and air flow meter - it's had a nasty crimp in it since I installed it and it really wasn't the best solution. A 45ยบ elbow 80mm to 70mm reducing silicon intake hose was purchased from Demon Tweeks as well as a 19mm O.D. Revotec self-sealing take hose off from eBay. The silicon hose comes with enough length on either end to trim it to fit. I then fitted the hose and mocked it up in the engine bay so I could figure out where to fit the take off for the hose that runs to the ICV. After I was happy with that fit and had marked the point at where the hose should connect, I removed the j-boot and got ready to make the hole for the take off fitting. The kit comes with a neat punch that makes the hole for the take off. A quick smack of the rubber mallet and voila! Then insert the barb connector and tighten up the lock ...
