MSD Pre-wired SwitchThis prewired switch makes it very convenient to switch back and forth from conventional Kettering to an MSD ignition. It's useful for troubleshooting the MSD unit and it's wiring and for switching it back to Kettering so your ignition scope trace will look 'normal' for the easiest trouble shooting. It's the same four pole double throw switch we've been selling for this use for years. . . only not the delicate job of soldering the wires on the switch

Bought this for a fraction of the cost. An auto shop wanted to charge me $72.99 for a filter so I bought this Spearhead brand cabin filter and its the perfect size and its just as sturdy as the previous one the dealership had in the car. Not sure yet how the airflow is or if anything different as I have not driven in the car since it was replaced, but it appears to be a very high quality cabin filter for my car at a great price.

Good Quality Replacement for Lexus

Style: BE-285 1-Pack

Was a perfect fit for my 2016 Lexus NX200t. No tools required. Total of 5 minutes to install. Airflow is good after replacement and the activated charcoal seems to make a difference in reducing any smells from outside. Recommended.

Economical, easy to install, and does the job!

Style: BE-182 1-Pack

First, depending on your car model, replacing your cabin air filter is VERY easy. With that out of the way, the shop wanted to charge almost 65 dollars to replace my cabin air filter. Decided to just buy one and do it myself. The only downside of waiting is that the air inside the car is not as fresh/clean when you're running your air. Anyways, you can usually get these kinds of filters between 20-45 dollars from auto part shops depending on the brand and features. I've used this brand and filter for the past 3 replacements on my car and they last just as long and filter just as well from my experience. No issues installing, and does in fact do a good job of filtering outside odors. Highly recommended for the price!
