The short answer is the air intake most likely has nothing to do with the misfire. P0306 is recorded by the ECU when the plug is not firing correctly. Take a coil from the junkyard and put it in cylinder 6. Don’t get a new one off eBay, eBay coils can cause the misfire code. If you want to see what the air intake looks like, check out my post regarding spark plug replacement.
