From this thread

90915-YZZD1在丰田或凌志系列用于十多年前的六缸车,而90915-YZZD3为其八缸车所用,两者主要是容量【高矮】的区别,坊间一般认为只要油滤的安装空间够多可用大的替代小的使用,至于以大替小的优缺点就像机油更换周期一样众说纷纭,这个没有建议只能自己看着办,都是些陈康烂谷子的事情有兴趣去谷歌搜搜能有几箩筐。

Toyota 90915-YZZD1 [$6.01]

This filter is manufactured by Denso and is rather unique.  For starters, the cartridge has no end caps to speak of.  Each pleat is thermally bonded shut at the ends about 3/16" inward.  This was accounted for in the surface area measurement, however this filter still has the largest surface area out of the entire group: 160 sqin.  The main reason for this is the narrow core tube, which allowed for very deep pleats and thus a very long filter element.  A wide core tube is not needed for such a short filter.  The filter does use a plastic bypass valve similar to the Fram filter, however I could not make this one leak.  It is also held in place by a steel clip rather than plastic tabs like the Fram.

Toyota 90915-YZZD3:  [$4.05]

Pleated filter, resin-impregnated synthetic and natural fibers, 0.033” thick. 43 pleats, 19mm deep, with 80mm height. Seam is cemented on the inside. Ends of pleats are cemented shut but not enclosed in metal caps. 
Total area = 0.131 sq. meter[203.05 sq inches].

[Toyota 90915-YZZD3 203.05 sq inches vs Toyota 90915-YZZD1 160 sq inches]

Eight entry holes in base, thru which black antidrainback (ADB) valve can be seen. Looking thru the outlet, the hard plastic bypass valve can be seen at the far end.

Seating gasket is round O-ring with 70mm O.D., 64mm I.D., not crimped.
The steel housing is fairly strong, 0.016” thick.

Purolator Premium Plus L10241 [$4.12]

This filter is like most Purolator filters.  It has steel end caps, but with the bypass valve at the back of the cartridge.  The anti-drainback valve is a typical nitrile rubber diaphragm type.  It does not have the typical Purolator assembly string.

以上都是2014年左右帖子,2017年Purolator的质量控制会有改善嘛? 网购大致$4.12。

90915-YZZD1和Purolator L10241是Direct fit的,但网传后者过滤介质会有撕裂且过滤介质面积 160 sq inches vs 128 sq inches,价格是$6 vs $4。

Toyota 90915-YZZD1 - diameter: 2.92"; height: 3.38"; volume: .392 quart; media area: 160 sq in  $6.-

Toyota 90915-YZZD3 - diameter: 2.92"; height: ~4.1"; volume: .476 quart; media area: 203 sq in  $4.-

90915-YZZD3比90915-YZZD1: Volume +20% ;Media area +26%;Price -33%

简直没有天理啊!

以前一直用90915-YZZD1,这次准备买几个90915-YZZD3的试试,原本装在购物筐里的六枚Purolator已经哭晕在厕所.

Update:

The higher flow and larger the filter, the more time it spends filtering, and the less time it spends in bypass mode. Oil pressure is unaffected (if you choose a filter that has same bypass pressure as OEM filter).

Mobil One filters are already both high filtration and high flow in stock OEM size. The larger oversize M1 filter I use is massive over kill, but cost same as OEM size.

A larger oil filter needs to have the same specs (as OEM size filter) for threads, diameter, bypass valve pressure. Those specs are published at each oil filter manufacturer's website.

No matter what size oil filter you buy, you should always get one with an ANTI-DRAINBACK VALVE because this keeps oil in the filter when engine is turned off. This keeps filter full of oil, which reduces the time it takes for oil pressure to come up at cold start.

The anti-drainback valve should be standard on all filters, but is not. Cheap filters lack an anti-drainback valve. Quality filters (of any brand) have an anti-drainback valve.

So if a larger filter has an anti-drainback valve, being larger won't affect the time it takes oil pressure to come up at cold start.

With any filter, ESPECIALLY A LARGER FILTER, it is important to prime a new oil filter before installing it. Priming the filter prevents (or reduces) dry start after changing the oil.

Here's how to prime a new oil filter before installing it:

If filter mounts thread side up, do this to prime it: Fill up the threaded center hole with oil. Let it sit for a few minutes for filtration material to soak up oil. The oil level in the filter will drop a lot as it soaks up oil. Fill the filter a second time, then install it.

If filter mounts laying on its side, do this to prime it: Fill up the threaded center hole with oil. Let it sit for a few minutes for filtration material to soak up oil. The oil level in the filter will drop a lot as it soaks up oil. Fill the filter up halfway this time time, then install it. It won't make a mess if you quickly tip it into place and spin in on quickly.

The above is how my cousin primes oil filters. He's a mechanic. He primes all oil filters before installing them. However, he exceptionally thorough.

I doubt most mechanics bother to prime oil filters. If a larger than stock filter isn't primed, it's harmful because (if unprimed) it increases the time it takes oil pressure to come up when the car is started after an oil change. That causes a longer lasting dry start than you'd get with an unprimed OEM size filter.

With an OEM size filter, priming it (at time of installation) is very beneficial, but not required. With a substantially oversized filter (like I use) priming the filter is a necessity.

For anyone who cares about their engine and filtration, the air filter is the first line of defense. The oil filter is the last line of defense.
