Yes, if it's a genuine L1H1, with the right connector attached, and it's new, then that's a great price. Tell us where you got it!
The Autozone price is about $330. The dealer price is higher than that. On eBay they seem to usually be around $150-$200.
I won this off of ebay and it should be a genuine item, NTK brand at least and the colors of the wires are red,black,white,yellow,orange. I don't think that the seller has anymore left. I think this just happened to be the only one.
I think I saw that auction. It looks like the real thing. It's slightly questionable that it's not sealed in the factory plastic, but that probably doesn't mean anything. And it's a great price.
