4) SSR http://www.ssr-engineering.com/produ...intakemani.php


Did I leave any out?
Thanks!

 

j00 forgot the Crawford plenum.

For me, I'll be getting the AAM. I believe the gains were dyno'd to be almost the same as a full replacement plenum, it retains the stock strut bar, and is the cheapest of the bunch.

 

you missed the big one -- crawford

 

wait to see what 350evo and kinetix newly designed intake manifold does on N/A cars.

 

motordyne spacer.

 

Ouch, how did I miss Crawford.
Do you think I shuold reflash after any of these installs?

 

Crawford... I love my Crawford... its VERY easy to install... and the gain is big! + the sound that it makes w/ a popcharger is unbeatable!!! You wont go wrong with the Crawford...

 

Yup. I say wait a little. Personally, I like the new kinetix long runner manifold that should be coming out soon.

 

Wait a while...I know of a company that is coming out with a complete intake manifold replacement (very reputable) and it should be promising considering who it is coming from.

And yeah, wait for Kinetix N/A gains and wait for 350EVO to come out with their's.

 

Lots of posts about kinetix cracking...

 

not the latest version, v4....none have cracked that i have heard of.

 

^Theres a thread right behind this one about the Kinetix v5 cracking.

 

Well, consider the source... there isn't a Kinetix V5 out. They only got to V4. I can crack SS test pipes with a nice sledge hammer.

 

Installed my AAM spacer last weekend. Car has changed dramatically...

I was very skeptical at first, but thought I would take the gamble at $185 bucks. I have 400 miles on my spacer now after a road trip and driving to work. The car definitely pulls harder all the way through the powerband, it's kinda crazy. It growls more from the engine and makes an interesting sound when I hammer the gas, similar to a big-bike kind of sound and "everything" is currently stock from the headers back. All I can say is I have a big grin on my face and happy that I made the purchase. I am assuming all spacers or plenums will do this. I feel my intake might be contributing to this change too. It seems as if the plenum and intake are now in balance, before it seems as if the OEM plenum was choking a little on the amount of air. I do plan on getting a re-flash once the "entire" exhaust system is installed.
