Comparable to OEM and works on the first crank
This starter shape already mimics the original, meaning it should fit, and that it did! Installation was easy after removing the battery tray to get to it. Then remove the bolts from the starter and the connection then install and it took about 35 minutes to get it installed. We cracked it up and it started on the first start. Fit and functional is where the largest points are, and these are what makes this a good reliable starter. For the price it’s a great alternative to the dealer parts. So far the car is starting with no problems or issues.its construction is made of durable metal as it endures heat and cold cycles and to withstand rust and corrosion. It’s in par with the OEM and about the same weight.

Better than expected
I bought this thinking it was just like any other cabin air filter that fit my truck. It fits my truck perfectly. The Surprise was that it has a carbon filter side and is very well made. I can recommend this to you, and I will buy it again when it is time for a replacement.

Fit well
Seemed to fit in very well, was easy to install, and doesn't smell. I could see the charcoal beads on one side, which should help to pull out any contaminates; much better than the oem paper filters. Good value for the money.
