My apologies, 383/440. I have updated the post above and I've seen the article at Nick's Garage, but no part numbers are given. surfing the web there seems to be quite a debate between unsilenced (no snorkel) and one snorkel or two. I want the performance or HP housing, i.e. it could have come from the factory that way. -BD
