So I was on K&N's web site and I saw thay have a Typhoon intake for the Protege. Thay dont specify the PR5 or 2003 but I am asuming that if it is for the 2.0L then it will work. I did not get a price. Anyone got any info in this, how it compares with AEM. Well now I will have to rethink my descion on intake.....
