AVAILABLE IN POLISHED ALUMINUM

Our 4" inlet and MAF pipes are made with 16 gauge polished aluminum.  Instead of using a bent piece of pipe that rarely fits correctly, we use a straight piece of pipe and make up connecters to get the correct angles for a perfect fit.  These compliment and ensure an great fit when used with our Big Mouth Cold Air Induction Systems for the 86-7 Intercooled Turbo Regals. If you don't want to use this in conjunction with my cold air kit I will need you to contact me on what you are planning to use on the air filter end of the pipe.  If you are buying the inlet pipe separately, it will include connectors  for the turbo and one for connecting an air filter. A short sleeve will be included also. Some guys have just put a filter on the end of the pipe but the connector I include is angled for extra clearance. 

These are being made up after receiving numerous requests from customers running an engine management system that doesn't require a MAF sensor.

Clearance is real tight to the up pipe and I would also recommend relocating your IAC sensor as it would be right up against the rubber connecter that goes to the turbo.  Never could figure out why Buick designed it this way.  It is easy to relocate the IAC with an ANGLE BOSS that we sell.  This aluminum block makes the IAC angle over towards the driver's side of the car making servicing this device a lot easier.  I would recommend one even if you are running a 3" MAF pipe. 

NOTE!  In addition to the 4" pipes on this page we also offer a 4" ONE PIECE Air inlet pipe kit for those of you NOT using a MAF sensor.  CLICK HERE to go to that page of the site.

Running a 3" inlet turbo?  We supply these 4" to 3" silicone connectors that will offer a smooth transition to the smaller inlet turbos.  This is an option to go with our 4" MAF and Inlet pipes.  Be sure to check off this option if you need this connector or you will be shipped with a silicone 4" connector pm each end. 

Available with Black OR Blue silicone connectors!  Be sure to check the option box for which color you would like.  Also check the proper boxes if you want reducing connectors for the turbo or MAF sensor connections.  This pipe is normally made with 4" connectors on each end.
