RRE's EVO X AEM Cold Air Intake Information and Dyno Testing

Larger suction tube. It is a moulded edm rubber piece. Looks factory. OEM quality. The best fittings and connections I have seen on an aftermarket part.



Smooth inside compared to stock:




Filter is inside the box:




All done and buttoned up.



For So Cal it is the best thing EVAR with the poorly trained anti-import street racing police. You could paint the MAF pipe flat black and make your own lid for the box out of something with no logo. Officer Bob could stare at it all night long with a stupid look on his face and not know it was a highly illegal part that killed innocent people. 'Cause that is what they are looking for. They all know shiny pipes is what makes you street race boy.


Dyno:

Our Dynapack reads stock EVO Xs between 248 and 257 whp on cars running the second reflash. This is in line with Dynojet numbers I am seeing. Obviously the heartbreak dynos read much less.  But to use the argument of the heartbreak dyno operators... it is all about the gain, no?

Our Dynapack reads EVO Xs with full exhausts in the 270-280 range. Tuning with the ECUTeK software on these cars with full exhaust nets about 310 to 320 hp.

EVO Xs on our Dynapack with full intercooler piping and intakes, full exhaust, tuned using the ECUTeK software (yet stock fuel system) are running between 330 and 350 hp. These number are in line with other shops I am seeing here too.

That out of the way now ....

Here is a before and after. Before is a nice running EXO X with a full 3" no restriction dual exhaust system. No restriction after the DP if you know what I mean. Otherwise the car was dead stock with the version 2 factory flash.

After is with the AEM intake installed about an hour later. Note I am showing multiple runs, not the one miracle after run vs one bunk before run.




Here is boost before and after:




AFR before and after:




This intake makes great power. AEM spent a lot of time developing it over the last three months. They really do their best not to suck. Much of the power comes from  the car making a touch more boost and running a little leaner. On a dead stock car it would make less power with out the aid of the full exhaust.
