I got them from moi on here but here is the same kit DRIVEN Smog Block Off Plate Kit Honda CBR 600 F4 F4i 600RR 919 929 954 1000RR | eBay or Driven Smog Block Off Plates (Pair) - Honda - OPPRACING Products
it doesn't pop anymore but I done it for when I get round to fitting an autotune and getting custom maps done. it is also meant to lower the running temp but I wasnt out that long to notice.power wise its only meant to add 1lb-ft of torque so no big gains to be had there.
So if you just wanted to try out this mod without doing the full removal you could just block off the Pair intake on the bottom of the airbox??
Yea iv stuck bolts in the end of my pipes an didn't know about the pipe in the air box. I Spose untill I realised when I put it back on
you plug the airbox as well as the hole is after the airfilter and this is to stop cr@p getting in the hole and straight into your engine intakes.
