Was dissapointed.
They definitely tax the living crap out of your mid-low end power.
They do improve a little bit the last 1500 rpms, but it's a crappy compromise.

Aside from them looking nice under the hood, I would say $520 not well spent.

If you guys come across feedback for other products that you think we can save our money by not buying the. BecauSE of the benefit/cost factor, please share!

Thanks in advance
