I followed Richie’s guide on using a specific Honda intake kit and got lucky when I spotted a second hand one on eBay, chopped it down and bought a 90deg for the front.

This was sold as for a Prelude so that as well as a Civic/CRX.
Yeah I remember seeing that now,wot bhp is the filter able to take ?

Reason I asked as running 300+ bhp so need appropriate filter
mines fitted where you have yours should be able to use the one that’s on car as there isn’t much room atm for a bigger filter

Do you still get the nice carb intake noise with this box and that cone filter attached?

I’m running triple Jenveys with this box on and you get a similar noise to delortoes or webbers but much more crispier sound not sure if you can see the filter,it’s a bit of a bigun but is correct for 320 bhp which is wot I needed

There's a lot less induction noise with the airbox (compared to just open trumpets)

Thought so. But guessing still more than with the standard airbox? Especially on a 280z with FI still installed!

How on earth do people with open trumpets keep dirt from entering the engine? Or do they just take off the filters for photos/shows?!

I think no one does enough miles for it to matter. At 1000 miles per year, it'll be a lifetime before the engine fails.

I'm not running an airbox, and that's my sentiment for not. It would be different if loads of miles, in a dusty environment, but its not runnng in that. Nobody is cleaning their cone filter every year.... (or every 2 or 3 years come to that).

Though, I am going to fit an airbox, just not one of these thingies.

I got trumpet covers for mine. They filter the big stuff but not so sure about smaller dust particles. Don't really do enough mileage to worry about it though. Can't remember where I got them but I was from the US.

Farmer42, thinking about it, your mesh over your trumpets is doing more harm than good. As it clips on the outside, it totally blocks the function air trumpets were are designed for, for pulling air from around the edge/behind the bell shape. All yours is doing is pulling straight. I would try ones that sandwich between the carb body and trumpet.

If there was anything the shape of the carb inlet body on SUs I would give it a go. The ones you have put in your link won't fit as the shape is different. Also, Im not paying megabucks to import something.

I did think about the foam trumpet socks but they look naff and I thought they would block more air than the ones I have. My car runs ok so I'm not really that fussed about changing them.

Possibly these?

Did look at those but can't see much difference in what I have. I already have the trumpets so don't really want to spend another £80+ on some more. In fact i now have longer 75mm trumpets which seem much better. The short ones tend to suffer from drawing in hot air from the engine bay which affects the power. I'll stick with what I have.

I would have liked one of the Skiddell/PMac airboxes but couldn't see where I could route the intake pipe through the radiator panel. There is no room between the rad and the cabin vent pipe on my car and I didn't want to do away with the vent.
