I changed my oil today on my V6 Tundra (9000 miles). Third oil change for this puppy, one at the dealer (first one free), one with my dad at his place, and one today. I had intended to use a Ford Motorcraft FL-1A oil filter. This is a much larger filter than the original. Ive heard from another TSer (Ziggy454) that it would fit. Im not doubting his knowledge, perhaps it will on a V8, but I tried to put it on my V6 and maybe I could have gotten it to go, but I think theres just too much stuff in the way. The 1 qt sized Ford cannister was right up against engine block and close to some wires. I would worry that a hot oil filter close to wires would be disastrous. So I ended up putting on the stock size STP 3614 filter. Then she got 5.5 qts of pure honey goodness, Castrol GTX 5W30. Drive hard baby! I was hoping to put on a bit larger filter and go with 6 quarts of oil. So my question, has anyone WITH A V6 TUNDRA (v8 need not apply, sorry) found a larger than stock filter size that will fit? Is anyone using a 1qt filter? Is it close to wires and engine parts?
Secondly, the skid plate. I dropped it today to see if it would be easier to fit the big oil filter in there. I think it was pointless to remove the skid plate. Maybe it makes V8 changes easier, but are you V6ers dropping the plate? It took me long enough to remove and replace it, I could have changed the oil twice.
Thirdly (question for anyone who knows), what is the little plug with wire coming out of it just in front of the oil filter? I tried to get a pic. Im worried because its just tiny little wire and I might knock it loose when changing the filter. And a small part (1/4") near the plug is not insulated. What is this thing and should I be worried?
The wire goes to your oil pressure sending unit. I still let them change my oil so I can't answer your filter question, though I can't see a reason for removing the skidplate considering the location of the drain plug.
You won't be knocking the wires off your oil pressure sending unit when you change the oil. I wouldn't worry.
A hot oil filter won't do any damage to anything surrounding it (unless it's your bare hand ). It's not really that hot (nor should it be). But a manifold cover, now that's a different story!!!
You can probably get a filter that is larger than OEM but still fits in the area. Heat from the filter won't be an issue though.
You'd be better off going with a Pure 1 filter though in the OEM size than a larger filter or you can get a Pure 1 but get it in a slightly larger size also.
If you go with Amsoil I'm sure you'll have several larger choices you can get. Depends just how large you want to go.

Well I am worried because its just a tiny little wire and I think it could get knocked off easily when Im replacing the filter. And its bent at a funny angle, they should have routed it better. Im guessing its not good if the oil sending unit goes bad, oil starvation?
Here's a pic of the oil filters I described above, the Ford is just huge and I'm not sure its physically possible to fit it on the engine. A filter that is longer and slightly wider than stock would work I think. Would an oil filter not get hot enough to melt the insulation on a wire if it were touching the filter? It seems it could be 200+ degrees for extended periods of time...

All that does is send back the pressure measurement. You could pull it off (it's not easy - don't worry about it) and things would work fine (other than your oil guage). Sort of like covering your eyes and ears when a car is going by. It still goes by you just don't get the feedback. (the gauge is the feedback mechanism)
200+ degrees is not really that hot. The ideal temp for the oil is 176 degrees. Or is it 167 (can't remember). Occasionally it will get into the boiling range for water on a hot day but even that's still not really that hot. (well, unless you're working in it.....)
I just use the stock Toyota Filters for the V-6, I can get them for just under 4 bucks and they are a nice filter. You could use the filter that is stock on the V-8 Tundra too. I picked up one my mistake, or should I say the parts dept gave me the incorrect one my mistake and I had it side by side with the V-6 filter and they are a little larger, have the same pressure relief rating, just a little larger filter media. When I took it back the smart dude was at the parts dept. that day and we took both of them new side by side out of the box and it was just a little larger but would fit with no problem. We both saw no problem with this. I tried to start a thread about this some time ago but didn't have any support. I will say that in my 1988 toyota 22R I used the PH8A filter size (1Qt.) for over 300K and I just switched back to the Toyota filter that is smaller but this is because I have three trucks that all take the same filter and it is a lot easier because I buy them whenever they are on sale. I know that when I got the 1982 new it was the stock filter size but sometime during the late 1980's all the books switched to the smaller size. One thing that I am really impressed with the toyota filter is that if you let the truck sit for sometime and change the oil without starting the truck the PH8A filter size all seem to drain back to the pan and the Toyota filter is always full.
The TRD filter is a 1 qt filter the size of a PH-8A or a FL-1A isnt it? Is the TRD designed to fit on a V6 as well as a V8? If so then I guess this FL-1A should fit on there, it just seemed like it was too bulky.
For my dipstick to read full it takes 5 3/4 qts. The leftover 1/4 of a qt I dump thru the engine after the pan is empty to "rinse" whatever junk is in the pan before putting the new oil in.
Hmm thats a good tip, rinse the junk out with extra oil. Ive read on another thread that a Purolator PL30001 is a slightly longer filter that will fit on our trucks. Ill check it out next time Im at the auto store. The PL30001 is specified for all Land Cruisers up to '96 in case anyone wants to reference the part in the filter book at the store, like I will do. I want to know if motorcraft, delco, and/or STP also make an equivalent slightly larger filter.
I've been reading this thread and want to learn something -- will a longer filter affect the backpressure available to move the oil around in the engine? And wouldn't a longer filter lead to an inaccurate oil level on the dipstick since some of the oil would be sitting in the longer filter? Also, I've been theorizing that a longer filter would affect the ability of the engine to keep all its parts properly lubricated as more oil is being sent to the filter instead of being promptly returned to the engine as in the stock filter?

I have no technical data to answer your question. What I do know is my common sense, though of course I could be wrong. Toyota sells a TRD filter that is about 2x the size of a stocker(see my link above for comparison). AFAIK, it just gives you more filtering capability and the capacity to add a bit more oil, so I suppose it would take a bit longer to break down. I dont think the dipstick would be inaccurate. It just measures resting oil in the pan. The necessary amount of oil to be between "low" and "full" on the dipstick varys by a quart or more. Its not gospel that you have to fill it to full, its just supposed to be between the dots. You would add a bit more oil with a larger filter and it should read the same. And a larger filter wouldnt keep oil from the engine parts, because if the filter is full you still have that extra oil that makes up for it. And I could argue that a larger filter with anti-drainback valve holds more oil for cold starts. There is a "flow rate" or something that deserves consideration when choosing oil filters, but I dont know much about it. And AFAIK most filters fall within a certain range and Im not worried about it. Toyota has/had made 3-4 different filters for the Tundra, they cant all be exactly the same ya know? And they probably vary filter to filter. All toyota pickups used to use a huge 1 qt filter, now the books specify the smaller one for the exact same trucks. Thats the cool thing about Toyota, all trucks for about the past 20 years use the same filter (save LC up to '96). So use whatever filter floats your boat.

1) There is no backpressure involved in lubrication.
2) The oil pump puts out an almost constant volume of oil after the engine gets up to speed and up to temperature. The oil flows through the oil filter...the size doesn't matter.
3) The dipstick measures the depth of oil in the pan. Yes, the bigger filter holds more oil, so you need to add more when you change the oil so the same depth of oil remains in the pan.
4) The flow of oil is from the sump (pan) through the pump, through the filter, and then into the engine's various parts. From each part that gets oil, the oil then falls back to the pan. The size of the filter makes no difference--the oil flows through big and small filters at the same rate, i. e., the rate of the pump output.
I don't understand nearly everyone's desire for oversized filters. The stock size works fine. My filter has been on for 10,000 miles and the oil analysis is excellent. The filter isn't clogged with debris nor bypassing oil except when it should.
