Yes, they are direct replacement for the stock ones.

I'm using the 725's but haven't fired it up yet.
Had to reuse the stock top and bottom o-rings.
Fitment is perfect and the P&P plugs are nice.

 

evans-tuning sells them along with T1, not sure who else sells them. I have them and love them. Although i cant speak from the tuners standpoint but i can tell a huge difference with how well the car runs. Its smoother than when i was on stock fuel system and ecu.

 

I bought mine from T1 back when he was teh first to sell them....as stated Jeff stocks them as well.

Both excellent places to shop.
