Always one to look at saving a few pennies with DIY mods.
So, done a bit of research a while ago into the Apexi Induction Kit.
I had seen good results on the cars I had mapped, so thought it about time I tried one myself.
I didn't fancy paying £150 for one of these, suitable for Impreza 1997-2000 :
When for £45 you can get one of these :
Apexi Power Intake Replacement Filter
£3.49 for 1M or steel from B&Q a bit of bashing and save yourself £100.
Bracket to stop MAF vibration
Mounted to Alarm Bracket
All Painted
