I have a 3" K&N Air Filter. Generally I have a 3" intake to plug it on and it's all good, but to pass smog, I need to use the stock intake and MAF, so I need either a stock airbox or a MAF adapter to hook up. I don't get on here every day, but hit me up with a price if you got one and I'll try and meet you asap. I got my bike registered, now it's time to get the eclipse registered, dammit!
