Alta Open-Element Intake
Peak wheel-hp: 172 @ 5600 rpm
Peak wheel torque: 183 lb-ft @ 4350 rpm
Maximum wheel-hp gain: 9 @ 5900 rpm
Maximum wheel-torque gain: 10 lb-ft @ 3200 rpm
*Install process: Removing the stock airbox is straightforward and painless, removing a couple of screws that hold the box in place and then removing the clamps on the stock hoses. The new intake shroud attaches to factory mounting points and includes a new elbow to connect the filter to the MAF and a coupling for the factory intake. Installation time is about a half hour to an hour and requires basic hand tools.
*Pros
Well-built components made from quality materials A little more intake noise along with a whoosh from the diverter valve could be good (or bad) Makes power across the rev range
*Cons
We'd like to see the filter shrouded from engine heat and maybe an intake funnel inside the filter to smooth flow before the elbow
*Notes: The intake showed a measurable gain across the entire powerband and definitely improved the sound. The stock airbox is nearly adequate for standard amounts of boost. This is one of those mods that will come into its own when more changes have been made.
