Parte K&N correspondiendo con el filtro de aceite SuperTech ST4967

I just received my filter by FedEx. Amazing. From California to Abu Dhabi, United Arab Emirates, in less than two days. I will give a more in depth review when I have the filter installed.

Greatest aftermarket filter out there. Will never use any other filter...ever!

I would highly recommend using K&N oil filters.  I started using synthetic oil in my 2008 Toyota Matrix and changed the oil every 5,000 miles.  At first I was using stock oil filters on the car but began noticing that around 4,000 miles after the oil change the cars horse power would significantly drop and on cold days the car would run ruff.  I changed out the stock filter for a K&N and as soon as I took it out of the box and compared it to the Toyota oil filter, I knew the K&N product was a much better filter.  Since I have been using K&N my cars horse power does not drop off after 4,000 miles and ruff starts and performance on cold days is no longer a problem.  I can usually pick these up for about $15.00 and they are well worth the money.  I'm confident that synthetic oil and K&N oil filters will keep your engine running like new.
