  • Lobe Separation Angle: 107°
  • Hydraulic flat tappet design for reliable operation
  • Aggressive idle and strong mid-range to top-end power

Key Features:

  • Produces the signature "Thumpr" sound with a lopey idle
  • Optimized for street performance and aggressive street/strip applications
  • Works well with aftermarket heads, intake manifolds, and exhaust systems

Fast shipping cheapest I could find, easy to deal with, great product

I ordered my Auto Vent Shade bug deflector 18174 on Thursday afternoon, June 14, 2012, and had it on my front porch by Tuesday, June 19, 2012. I thought that was fast shipping, especially considering there was a weekend involved. The price was also very reasonable. I am anxious to install my new bug deflector. I will be turning to Autoplicity in the future for my auto needs. Great Job Autoplicity!

Very good prices and good shipping prices. found my parts cheaper then any place else. Thanks to Autoplicity for filling my order #8498 of 4/02/12 quickly and accurately. I will be back.

The item has not been delivered yet. But the email updates are great. And I found this much cheaper than elsewere.
