540 3.5" HFM Part Numbers

Part # 02802178001702078

Is this correct? Some I see end with 800 or is it the same?

Also, is there really a difference you can feel with it?
Thanks for your inputs.

You know that you can't just install a 3.5" HFM and see gains, correct? You need injectors and a custom chip as well.

Yes I know that....just trying to confirm the part #

Did talk to Active and Turner though and both said injectors can remain stock unless cams are upgraded, both sites offer these upgrades minus the injectors - CAI, HFM and Custom Chip is being sold as an upgrade kit

I stand corrected. I didn't think just moving to a 3.5" HFM would provide a worthwhile benefit as long as the other parts remained stock, especially the stock chip.

RealOEM has the part number as - 13621702078
