I know, I added it all up last night and with the total price of the silicone joiners and the different pipes, you might aswell just buy a fucking ready made full kit you aren't saving anything. Your engine mods are the same as mine then, atm I have NGK plugs, NGK leads, and Corolla intake mani. Maybe I'll just ask the plumber at work if he can get me some 3 inch PVC pipe, and a long 90 degree bend lol then I'll wrap it in heat reflective tape and job done
