Northstar Throttle Body kits for 96-99 M90
 

Time is running out on the preorder and i want to make sure everyone has a chance if they want one. if you go to the vendor section there is a post with all the information for buying a kit and the options

Whats the difference between the straight through and tapered designs?
And which maf is the Northstar Maf?
Will the maf tables need to be reprogramed to use?

the straight through plate is meant for ported M90s. the plate is 75mm. the tapered plate is 75 to 72 mm which is the TB to the stock inlet

the northstar MAF is similar to the 96-98 L67 sensor.

Putting the MAF tables into the PCM is better then using a power tuner or mini AFC will be required to tune it up just right.

I have had alot of success using the LQ4 MAF and table and using the N* MAF witha mini AFC.
