Weapon R intakes are all short ram. My friend bought one and we extended into a cold air intake with the right piping and materials.

 

im looking at an injen CAI for the 05 rs does that work for the 06?

 

Yes it will work.

 

thanks

 

ok looking at a AEM for 04-05 rs should that fit well

 

NO!

00-01/02-04 2.5rs use a MAP sensor, 05-07 2.5i/wrx/sti use a MAF sensor


so a intake from an 04 2.5rs will not work on 05+ impreza of any model.

i, myself, modified a wrx aem intake to fit on my 07 2.5i, it was a pain in the *** to do, but it works and does the job

 

for a WRX or for a 2.5rs? cause the WRX one will not fit on the N/A cars and is not worth getting. just buy an AEM or Injen for the 05 2.5rs and use a T connection to split one of the vacuum lines (the new 06-07's have an extra hose connected to the intake)

 

would the 03-04 cobb intakes fit the 06-07 2.5i's
