A K&N filter offers about 1 HP gain so you won't 'feel' it but it can be used for many years with just a washing and reoiling and it does filter much better than a paper filter. Worth the money but no, not a HP increase that you'll notice.

Advancing the timing to 14 degrees is free and you will notice the difference.

3.73 or 4.10 rear axle gears are a great mod but run around $400. with pro installation (highly recommended).

Underdrive pulleys are under $100. and offer about 5 -8 HP gain but as mentioned, you could have charging problems.

Always do a full tune-up on a newly aquired car. Plugs, plug wires, cap, rotor, air & gas filters, TPS adjustment, timing.

Good luck with your 'Stang!
