Does installing a ZZP intercooler kit help is resolving issues with the TMAP sensors? Does it provide more clearance or a better seal for the o-rings since the pipes are metal and not plastic?

Are there some piping kits that are better in relocating the sensors than others?

I just turned my lower tmap sensor 180 degrees on my stock pipe.
You have to grind file or mill down the flat part that is on top of the mounting pad.
Also you have to make up some brackets to move the radiator forward
Worth the time though no way the engine can hit.
I believe fool on was. The first to do this
Others will be along soon to give more info on the aftermarket pipes
Here is a link with a lot great info.
