In the interest of shining a light on the OEM vs aftermarket truth, I wanted to show off a little something I noticed during my travels. Not too long ago, I replaced my timing belt, pulleys, hydraulic tensioner, and water pump on my 2005 Subaru Impreza RS 2.5 SOHC (booo no turbo, I know, I know, it was a good deal). As you can imagine, I got part number GAEEK00038 from 1A Auto (Hey, I can throw a subtle ad in here if I want, amirite?) Anyway, the timing belt kit that I purchased was made by Gates, who is a very well known, and reputable brand in the auto part world. When I opened the box, it was a bit of an “Ah Ha!” moment. Mixed in with the Gates brand water pump and belt, were OEM pulleys! They had all the same markings as the OEM ones that I pulled off of my Subaru. Yes, 100% totally identical in every way. Cool right? (New ones on the left, old ones on the right)
Much like I had seen in the past, even though it is considered an “aftermarket” part, it may actually be OEM. Now, obviously this is not the case every time. In fact, I would say that it is the minority. But, hey, it happens more than you might think. Beautiful “aftermarket” …ehem… OEM… parts at a bargain price!
Last week, I decided to replace the ol’ spark plugs on my 2005 Subaru Impreza RS. While the car was running perfectly fine, I figured that they were due since the car had 105K miles on it. Luckily for me, yanking the spark plugs out of a non-turbo Subaru Impreza is completely drama free. Within a few minutes, all of the old ones were out and they clearly looked worn out. Their gaps were twice what the factory called for, and then some. It’s really amazing that the Subie wasn’t running rougher.
Before long the new spark plugs were tossed back in, and I was pleasantly surprised to find a noticeable difference in engine smoothness at idle, and while accelerating. I hadn’t realized that it wasn’t smooth before, until I felt the new smooth. Sure enough, the new smooth is considerably better. I’m hoping that this will gets me the other mile per gallon that I need to hit a consistent 30… We’ll see!
First off, LS series engines are a new obsession of mine. Secondly, I just so happen to own a Subaru Impreza. So, it seems fitting that I post up a video of an LS engine swapped Subaru. The video claims LS-2, but I think it’s actually a cast iron 6.0L LQ4. Be sure to crank your volume way up for this one. It sounds delish.
