You do have to tighten them more than a stock filter. The quad seal, which is reusable, is harder than the stock filter seal is my guess why it has to be tightened a bit tighter. I don't use a torque wrench but snug it up with a 3/8 ratchet because the K&P filter has it's own filter wrench with 3/8 drive hole.
I've been using the K and P for quite awhile, bought it from Jaggs the same time I got a cooler. A quality made unit and the quad seal lasts a good long time. I torque it to spec and it certainly won't be rattlin off goin down the road.
Thanks for your opinion on these filters. I have one more question. When you install the filter do you add a little oil inside the filter like some people and myself do with a normal oil filter. I think because there is no drain back valve if you pour oil into it before installing it wont it just pour out before you spin it on??? And if you don't add oil wont there be a lot of air to bleed through before the filter fills up with oil???
Just trying to cover all my bases before I spend 150+ and then be nervous about installing it and letting it sit on a shelf. tia swifty

I used to fill mine up a little less than half full before installing...never had any leak out when installing it.
Now that it is relocated (see pic above), I fill it up to almost full.
No need to spend 150+, look at this LINK, it is a better set-up than the K&P with a nut on the end for easier on/off.
Just bought one for my end of season change. There is an older thread on one of the forums here that was helpful in making my decision. I like the idea of less waste, diagnostics, the fins for a small amount of oil cooling (it all helps), and the nut on the end of the one I bought for easy on/off.
There is no benefit except it sounds like a Hoover Vac above 4K...If you look at that small hole in the throttle body, the original filter has more then enough area to let air in. Engines do no suck in air the same way they compress it out. The only thing that a normal non turbo or supercharged engine does is let air in from atmospheric pressure rushing in to fill the void. It does not even flow fast enough to pull raw oil dripping from the vent tube..just the air. (You will see a slight film after a whole lot of miles since some is so hotly vaporized that it will film the throttle body. )

This brings up another potential issue. Since there is no drain-back valve blocking reverse flow, there is the potential that debris stopped by the filter will drain back into the engine when the engine isn't running.
My guess would be that most oil filters have anti-drain-back valves, for very good reasons.

I said the same thing about the drain back valve too. But on the K&p website in the faq section. They put it like this, take your old oil filter off and lay it on the side the oil will still drain out past the valve slowly. So if something that 40 microns small will still come out and rest in the crank... That makes sense to me. Also these thing have earth magnets built into the filter!!
