Ihave a 1989 saab 9000 Turbo
Ijust did my intake over about a week ago
it gives gains on the low end 2-5 Hp
what i did was cut my airbox and put in a high performance spectra air filter in ,so my airfilter is sitting in the open which gives much better airflow but im going to do my exaust next to and people say the cone filter will give more air and the exaust will let it out faster giving alot of gains 20 25 so i think you should do the airfilter man
