The key is the cost benefit of a mod and the general consensus is for NA the cost is high for small benefits. Whether it’s worth it, depends on your wallet and what you want out of your car. I am staying NA, so headers, air filter, tune and power blocks are it for me powerwize. Suspension mods, tires, lightweight wheels will be my focus in the future.

100% agree. As long as the person behind the wheel at least understands that the results of his work haven't made it 221HP record holder and much of what he feels is just perception.
