Intake manifold

I finally got around to getting a 2.4 manifold this week, installed it yesterday. Really don't thinking noticed much of top end gain... Deffinately felt the mid range drop, but don't really know if it was worth it. Hopefully it'll feel better if I ever get around to getting it tuned.

5 speed. Injen short ram, now the 2.4 mani, zzp long tube and an lsj exhaust. Had a magen cat back but I got sick of the noise.

I felt more of a difference when I went from a CA header and 2.5 catless dp to the zzp long tube.

The fall in power after 5000-5500 should be gone, more linear pull to 6500

i'm assuming you unhooked the battery after/during the install?

After having it on for a few days I can honestly say it made a difference, not huge holy crap why didn't I do this 4 years ago difference I was expecting because of how much every one talks about the difference, but it did help. The zzp longtube was a way better buy.
The biggest gain I noticed was at half to three quarter throttle, not wot. Driving around and keeping up with traffic, once the rpms are up or some spirited driving, huge difference.

the car does great with proper snow tires. i tried the factory ones at first, but barely got out of the driveway. lowered kinda sucked, definitey only went down roads that were well plowed, so i was limited as to where i could go when icy. but i only did that for one winter. factory dp used to leave snail trails in the middle of the road on snowy days.
