Power Tower worth it?

[SilverBullet]

Is the Helix worth it? I am wondering if I could fit a throttle body spacer on my truck? I have the bug, and now I want to drop a LT/LS1 'vette motor into my old 280zx! Probably gonna have to sell it though!

One member here, Red Sierra, had one and took it off.  I believe he said all it did was create a high pitched whistling noise when he mashed the gas.  No noticeable gains.  You could PM him to double check but he's the only one here, who's had one and reviewed it, that I'm aware of.  You might consider a new exhaust system to compliment your K&N.  And by the way, Welcome to the Forum-
