Charge pipe advice [fitting]

I have a Aktive Autowerks chargepipe and BOV in a hope it will cure my boost leak.
Is it a difficult job?

Any fitting guides on here that anybody know of?

thanks

are you sure you got a boost leak there? do a smoke test , boost leaks can be anywhere.

Yeh ran a smoke test and no leak although a smoke test will not detect a leak in the diverters so this is the next point to check.

Smoke test won't do anything unless its pressurized to atleast 15 PSI. I agree boost leaks can be anywhere. Multiple vac / boost lines, intercooler connections, throttle body connection, boost tubes, solenoids etc

Installing a charge pipe is very easy.

Yes, you connect the CP to the cold side piping via the provided clamps, make sure they're on tight. The throttle body side attaches via the stock C clip, wich you pull off of the OE CP. Be careful getting it off, it doesn't require a ton of force, and can be broken if you pull or yank too suddenly or at a strange angle. Inside the OE throttle body side piping youll find a rubber o ring, yank it out and place it in the same section of the AA pipe. Throttle body connection is just the opposite of removal, and you're set in terms of clamping for the CP. Just gotta deal with the MAP, connecting the line to the manifold, and capping off the intake holes from the diverter valves. Takes a little bit of time, but pretty simple all in all. Be patient and try not to lose anything, my car's engine bay ate a screw last time I was in it

google "active autowerke bov pdf" and the first result should be a detailed DIY instruction set from AA themselves. Install is 90% identical to my ER chargepipe, but there you have it from the horse's mouth. GL and be patient.

Cheers mate, organising another dyno day so hopefully we will both be ready for it. Plan is to fit the charge pipe on Saturday.

Thanks for the tip.

Going to get something turned at work. Rough idea on internal size or is it better to taper it?
