Key Features:

  • Head Diameter: 2.080 in.
  • Stem Diameter: .311 in. (5/16")
  • Overall Length: 5.010 in.
  • Installed Height: +.100" longer than stock
  • Material: NK-844 stainless steel — exclusive Manley intake alloy not offered by any competitor
  • Chrome stems with hardened valve tips
  • Fully machined and swirl polished for superior fit and finish

2005-2009 Subaru Legacy

Great prices and great products. When it was received, the merchandise was correct and packed well. Thanks, will be ordering oil from this buyer from now on. (order #5647)

Your website said that these would not fit my vehicle. However, every other site says they do, including the manufacturer's website.

Easy checkout with Amazon

Fast shipping and saved $60 on a $399 item. However you have to verify your part #'s with the vendor. The part discription on autoplicity sometimes is not what you get. I ordered an item that said it was an O2 plug and bung but when it showed up it was just the bung plug sold separate and customer service basically said it was my bad for not checking for a more accurate discription on the Allstar web site.
