No you don't have to. When you start adding headers, exhaust, porting and polishing your head-when you start to really open up the airways or forcing air in ie: turbo or supercharger, then the fpr will help along with a good ignition. At this point, I say no you don't need the fpr.

I have an HF and I got a regular intake that is universal for CRXs and I opened up my exhaust with a custom fit. Got a lot more torque and it sounds great. All for the price of 250. ( I needed new exhaust anyway.

Toss in another 300 or so and you could have gotten a ZC.

My HF motor has 55,000 miles on it and I get 44 mpg. I'm old enough not to have the need for speed, just some pep(gotten the inexpensive way) and good gas mileage. If it had 155,000 on it, I would swap it out.
