Anyone out there have any experience with the Tapered " Spike " air cleaner kits from China that are all over E-bay ?? They look great in the pics and the price is almost too good to be true. They go for anywhere from as low as $110 to about $175. I found one place that is in the US that has them for $159. I'd feel better buying from someone in the US even if they import them. Their feedback is 98% good. I'm just curious if anyone has bought one and how the quality is ?? How do they fit - is the chrome decent ?? Thanks in advance for any input.
