I DID A SEARCH AND REALLY DID NOT FIND WHAT I NEEDED.
WHAT I WANT TO KNOW IS ARE ALL AFTER MARKET INTAKE THE SAME. TPIS WANTS A HEAP OF CASH FOR THEIRS, EDELBROCK, NOT SURE ON PRICE. BUT I DID SEE AN ARTICLE ON THE EDELBROCK, AND IT WAS A MATCH FOR THE STOCK INTAKE.
THE SAME THING. NOW NOT SURE ON TPIS, BUT THEY SAY THEIR INTAKE IS BIGGER THAN STOCK. WHO HAS ONE OF THESE INTAKES, AND ARE THEY HAPPY WITH IT. I DONT WANT TO CHANGE MY TPI FOR A MINI RAM,OR STEALTH RAM, I WANT TO PULL THE MAXIMUM I CAN ON THE TPI. THANKS

 

the tpi has a ton of restrictions so you either have to do some heavy porting where in the end you will still be limited. Simply put the mini-ram is the best efi intake for our cars. Everything else falls somewhere in between

 

To answer your question about the TPiS intake being bigger. Yes it is. It has larger runner ports than the stock TPI base ports. These are for better top end power as well as low end grunt. They made this intake to mate up perfectly with their Large tube runners. Their runners have larger ports as well as a longer runner length to increase torque. If you do decide to go this route they will port out ur upper plenum for you to match up with the runners. I think people have seen 20HP/30TQ gain over stock TPI.
