Northstar Engines and System Technical Discussion Discussion, Performance Air Intake Kits ? in Cadillac Engine Technical Discussion; Anybody here try these out . I saw a kit listed on ebay , the price doesn't sound to bad ...
I bought one similar for my 2000 STS. The pipe was smaller than the TB size and there was nothing to fit it to the Mass Airflow Sensor. Your STS doesn't have one, but that's just something to be aware of.
The MAF is almost 80mm and the TB is like 70mm or 72.. all of those intake pipes are 3" which is smaller than the MAF opening.. I e-mailed a bunch of the 'ebay' el-cheapo air intake kits and nobody had anything > 3".. I'm designing a new intake and having a shop custom make a tube and claps (silicone) for me..
