Kyosho Gx-15 air filter

[Siw]

I’ve got a GX-15 engine on a car which was ran in approx 15+yrs ago, but hasn’t been ran since.
id like to replace the air filter, but an unsure of a cheap/good replacement… any recommendations?

also i believe the engine was ran in on 20% fuel (from memory), what fuel should I be using?

I'm not a huge fan of nitro but there is a few guys in here that are very knowledgeable with them. They will chime in.
