K&N oil filters due to their construction have gained recognition of the most demanding drivers and are one of the few used in competitive motor sport. These filters are distinguished by a filter layer which does not limit oil flow.

For screw-on filters, the benefits are:

  • Reinforced external wall construction reducing the risk of mechanical damage
  • Head for easy filter operation using standard spanners
  • The hole in the head allows the installation of the pin required in many motor sports disciplines

An additional advantage is the internal valve closing the flow after a pressure drop, which protects the engine against dry start.

K&N sports oil filters are an ideal solution for all car users who care about the efficiency and safety of their engine and are looking for the highest quality products.

The filter is dedicated to the following vehicles:

Great Multi-Function Watch
Color: Gray/Digital/Gray
I absolutely love my Timex Ironman watches. I have had many over a very long period of time. Wonderful set of functions for the price. Very affordable. Easy to use. Lasts a long time. Very easy to read in standard lighting. I like the Indiglo when needed, but do not use it too often. Absolutely love the ability to set a repeat timer to remind me to do something at a fixed interval, or to keep me on task for a fixed period of time. Great to be able to set three independent alarms. Potential to capture a huge number of splits with the stopwatch. I purchased this watch to replace a similar model with a dead battery. I have replaced batteries in the past, but it is quicker and easier to buy a replacement watch. I am saving my old watches for that day in the future when the Ironman model may no longer be available. I expect this will be my watch of choice for the rest of my life.

Just fine if you have simple needs...
Color: Black/Digital/Black/Green
Exactly what I needed: a cheap, durable wrist watch. The only thing it was lacking were instructions, but about 5 minutes of messing with the buttons got it set up

Compared to g-shock?
Color: Black/Yellow
Firstly random public reviews can be comical…”it’s has a battery, terrible, One star” or “I don’t like yellow, one star” omg peoples do better. I’ll review this while comparing to an older style of g-shock from the same era. I’ll start by saying this timex rocks, for me in my mid 50’s it’s so retro and nastalgic, brings back memories, I may have even owned this model back in the day. What’s great about it- the display, larger digits than the typical g-shock and they are super crisp, clear and easy to read. The indiglo is awesome. This is the most accurate quartz watch I have aside from the atomic g-shocks that adjust themselves daily. I prefer a chunky watch and the g-shocks do a better job in that department. i feel this watch is rugged, but I’d still give the nod to g-shock in this department. 200M water resistance is the gold standard and this watch has it which I love for peace of mind for any water based activities. This is a 5 star watch at a great price. I still love some aspects of a g-shock better but its just preference.
