1965 GTO w/1968 Pontiac 400 drag car
Was running just a standard AC Delco PF 24 but wanted to upgrade to a racing oil filter
I thought a WIX 51069R would fit but the diameter of the gasket seal is to wide.
Any recommendations?

[Steve C.]

If it helps the PF-24 filter is similar in size to the WIX 51258 filter.

Canton CM filters. 8 micron replaceable elements. Available in spin on or remote mount. Different lengths depending on the clearance available on your application.

Any good filtration system must also take flow into consideration to determine an optimum balance. For example, a 45-micron filter is recommended for most lubrication applications, and 35 Micron for lighter weight oils —however thicker 50, 60, 70-weight viscosity racing oils can clog it. For these ultra high-powered engines using thick oil a 75-micron filter is recommended.

Here it is. Plug your stock adapters by pass and buy this filter with a by pass, done. K&P
Far and away exceeds the stock filters flow rate and micron capability . And you can easily take apart, inspect, clean and reuse. Race engines need oil filter inspection.

Stock type filters I have always run the Wix 1049. Its the filter for 60s big cars. Its longer than the part number for say a 69 GTO. That it why I used them. Barely fit with my headers, but fit.

[dv657172]

Thanks for all the info guys, The K&P is definitely an attractive idea.

I'm not a fan of cleanable oil filters. I don't own a ultrasonic cleaning tank, nor do I have a microscope with which to inspect the filter element after cleaning.

Flushing and blowing air through a filter mesh will remove most of the particular debris but not all and after each cleaning there will be more particular matter not completely removed. Which is fine as long as you run a differential pressure guage across the filter element and do filter cleaning based on the pressure differential and not on miles driven or passes made.

These filters catch much smaller particles than spin on throw away filters.
And the flow rate/ lack of pressure drop is incredible. Much, much higher flow rate.
They are FFA approved, lives depend on them.

That K&P setup is cool. Not sure if it is overkill for a street application.

READ my post on Canton filters above. I am not advocating the use of common parts house spin on filters.

Then READ my post between that one and is one. I don't require a video from someone trying to sell me something to influence my decisions. I've had a 30+ year career repairing, rebuilding, and installing high and medium speed diesel engines in marine applications. My decision making matrix is different than yours.

We've been running Canton filters since 1996 and we've not found anything better. Plus we like to support long time vendors of Pontiac racing parts.

I would pay Moroso or Steffs big dollars to make me the nicest pan on earth before I gave Canton a dime.
I bought a trick Steffs for 850$ and Canton not only wanted 5 race pans minimum but wanted over 1000$ each for them. AND they wanted pics from me to build it. They lost the info and had not made one in over 10 years.
So I am not too high on Canton these days. They made some nice pans in the past but apparently do not have the info to build one today.

Wow, sorry to hear that about them. I wonder if they had a change in ownership.


And for the complete story here's a big rabbit hole.

1- Treat each other with respect. If someone is being disruptive, notify the moderators and then ignore them.

2- It's not your job on BITOG to zealously defend or debase the honor of a brand. State your position politely, offer credible evidence or reasonable experiences, and move on.

The Fram HP Racing series was recommended to me by a long time fellow pontiac racer and engine guy. After some research, I started using them a couple seasons ago on my ~600hp street/strip engine. Just refreshed motor this winter and bearings looked like new- same experience he had after many years on the same motor.

This is not to say the bearings would have not looked the same given any other name brand filter... but I do like the HP feature of a screened bypass valve. You still have the benefit of the bypass (if factory is eliminated), which will at least keep any big chunks out if needed.

With that said, I do feel many of these things just make us owners feel better, and the average hobbiest engine does not really care.

Did you eliminate your factory by pass ?
Its good to know that they make a stock type by pass filter. Kind of like the old HO recommended Lee filter. Thanks for posting.
What is the part number for the Fram Racing Pontiac filter you run ?

[Steve C.]

https://www.fram.com/products/oil-filters/racing

The different sizes are noted in the link.


Not a recommendation. But fwiw, many years ago when racing we used a HP2 racing filter. And as research found, at lease back then, their racing filter is a different construction than the regular off the shelf Fram filter.

That's good because the off the shelf filter is junk!

[Steve C.]

I used the HP2 with no problem. Again, this was years ago. Now today do we make the assumption that the Fram HP filters are of the same low quality as a regular Fram filter ? I have no clue on that subject.

No matter what brand there will ALWAYS be complaints when oil filters are discussed

[Dragncar]

Well. I thought I would buy a HP2 and cut it apart and look at their construction. They are not being made anymore and you can not find them.
K&N makes a cross reference but has no by pass.
Wix make a cross reference, 51049. I ran the 1049 for years.
Anyone know what the 5 stands for ? Does it have a built in by pass ?
That info is not on WIXs website that I found anyway.
