Why not "build it"? Because I have not wrenched on a car in about 20 years and really don't want to start with fabrication and fit. Also, these are "made" for the car, so call me what you will but I just think it is a little easier and worth the $100 bucks or so.
With that being said, here is what I have 'found':
K&N is averaging $260+ dependant on site (seen it for nearly $400 on some sites).
Wiz for series III with 4" filter is $263.
Thrasher CAI with filter is $225 ($10 bucks more for "powerstack"- not certain about getting that but it's "free" if you get it from their ebay site)
So if you are telling me it is not worth the $40 bucks for wiz, I would like to know why other than the $$. Is it performance, difficulty to install, breakdowns, etc.
blowfish has one- why did you get Wiz instead of "something else"?
As a last note- going to go back to the forum to review purchase site recommendations.
Again, thanks to all- I really appreciate the feedback and comments. After all, the world would be a very boring place if we were all the same.
