Go read that. It is for a 2000, but it will still apply.

Basically, you're looking at almost $1400 for a measly & barely noticeable 11 horsepower. And that is only at a certain rpm. The rest of the power band? Basically no gain in the slightest. 7.8 torque? Again, worthless. If u got a tune up, with new sparkplugs, u could see the same gain.

Save ur money. But if u do not want my advice, just go look at the dyno results. And ignore the peak numbers. Look at the whole graph. They actually LOST power at certain rpm. Which means, slower acceleration.

And definitely ignore where it says ''substantial gain in power''. 6-7 horsepower here & there, is not substantial. It is pathetic.

If you're spending more than around $50 per horsepower, you're pissing ur money away. And that is the bottom line.
