Good Price, Easy Install 3 years ago
austinbeachy77349
Installed on my 08 LGT spec B, easy installation, no worries about oiling the filter. Acceleration after install was much smoother, and had better turbo sound.

Not what I thought 4 years ago
J_Pipe
Made well. Great look but you never see it once it's installed so it really doesn't matter. Car doesn't run any different. Same gas mileage as OE. OE made more sound (I wanted aftermarket intake sound without having to tune) and is almost half the price. Save your money.

Excellent filtration without the oily mess. 5 years ago
joejoe69
I have used APEXi filters for years from their dual funnel Power Intake to a few of these drop in panels. Their filtration capabilites are awesome and you don't have to worry about oiling them, which is detrimental to MAF equipped engines.

QUESTIONS & ANSWERS

  • Q: tune or no tune?  raymondravarra405713 years ago

    I know it would be beneficial, but would it hurt my engine at all if I did not tune it?
    • 0 of 0 people found the following answer helpful

      A:  We always recommend a tune for 08+ WRX/STI. If you decide to run it without a tune we are unaware of what problems could occur.

  • Q: Tune or no tune?  raymondravarra405713 years ago

    I have been getting mixed answers. some say yes, some say no. Which is it? I drive a 2011 wrx.
  • Q: How long will it last  Subirista6 years ago

    So i know this filter isn't reusable. But how long or how much mileage should it last?
    • 1 of 1 people found the following answer helpful

      A:  Unfortunately Apexi does not release any information on the specific mileage that this filter will last. I would recommend following manufacturer guidelines on replacement filters for this unit as well.

  • Q: Tune??  09WRXlover6 years ago

    I was reading online and I get mixed stories about drop inns. Does this drop in require a Tune??
  • Q: Sound Improvement?  iLaw7 years ago

    I have a friend that has a K&N panel filter. In his car you can notice the sound of the turbo and the BPV more. Will this have the same affect?
