Having a look at fitting the air filter now, bought an itg foam one with backplate. Hoping it'll be big enough but also blend in. They do a domed filter that fits the plate I have so I'll probably end up with that rather than the squared one I have.
Back plate for the air box is mostly done, just need to fit the water injection nozzle. Not sure if its the ideal velocity stack but I can always trim it down. Need to decide on the straight or domed filter before I trim this one to fit.
That will hurt flow but if you want some of the flow back get a length of small bore rubber hose 1/8 or 3/16" ID will be fine - length same as circumference of the ram pipe and split it along its length. Dress the split over the end of the ram tube and glue in position - instant rounded edge will help flow and cost pennies!
