Intake air system

[Silverstar]

The sound of k&n is very nice but I want to try to buy the original pieces (used) on ebay.com
I am very grateful for your answers and the aid

I think the bottom one is the truck intake and the top is the SUV intake. They made the SUV intake to be quieter than the trucks.

I have a stock intake tube I'm not using, but I still have the stock box installed. Shipping something this bulky to Italy might be a little pricey.

I've ordered the intake tube p/n 15060999 from "nos" parts seller on eBay and used (but in very good condition) air filter box w/ adapter for MAF...
Thank you anyway, Justinlw
