OUR 3.5" MAF PIPE
WITH THE LS1 CHEVY MAF SENSOR INSTALLED ON MY GN.
SILICONE HOSES ARE NOW
STANDARD ON ALL OF OUR MAF PIPES
AVAILABLE IN BLACK OR BLUE
Our 3.5 INCH MAF pipes are
available in 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
adapters to get the correct angles for a perfect fit. These compliment and
ensure an exact fit when used with our Big Mouth Cold Air
Induction Systems for the 86-7 Intercooled Turbo Regals. They can be also be
a cone filter attached to the end of your MAF sensor.
These will fit the Chevy LS1 3.5" MAF
sensor and are designed to be used with either the stock type removable inlet turbos OR the
integral inlet turbos.. he pictures above show the
3.5" MAF pipe
installed on a 87 GN. It has a Chevy LS1 MAF sensor and TA49
A recent customer requested a 3" MAF pipe to
fit his 3.5" LS1 MAF sensor. To make sure everything would fit
properly I bought one myself and converted the GN from the Impala SS 3" I
had been previously running up
to the bigger sensor. While I was at it I figured why not make a 3.5"
MAF pipe to go with it! Finished fitting everything and it works out
great. Clearance is tight to the up pipe and I would also recommend
relocating your IAC sensor as it would be right up against the rubber adapter
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 available from www.BOPengineering.com.
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. Please note that I have a
1/8" Power Plate spacer installed under my upper plenum but I believe the
3.5" pipe will still fit with a stock setup. I would recommend our 3" MAF pipe if you are still using
the stock MAF or the 3" LT1 MAF. This pipe is to take advantage of the
larger 3.5" MAF sensor.
DIFFERENCE BETWEEN REMOVABLE
INLET AND INTEGRAL INLET TURBOS
Here's a good pic of how to tell the difference between a removable inlet and
integral inlet turbo. The turbo on the LEFT has an integral inlet and is a TE series. The
turbo on the RIGHT is a TA series, notice the bolt on inlet bell. (click
