I'm back to using filters. I gotta figure they make a decent enough filter. And since I change them EVERY oil change, I'm pretty safe. Just costs more than using cheapos.

 

So then are you saying K+N filters don't have that stop to prevent the oil from flowing back? I replaced mine with a K+N when I did my first oil change along with synthetic. I thought the K+N filter had the stop. Does anyone know how much the Mitsu filters are? I'll call the dealer tomarrow. My guess is I have to get it through them or is there somewhere cheaper?

 

The K & N does have the stop. I avoid my dealer like the the plague, so I'm not sure how much they're charging for filters. But, I did come across a fantastic deal on eBay: crate of 10 OEM Oil Filters and 10 drain plug gaskets: $50 to my door.

 

It is called an Anti Drain Back Valve and it should be in any filter manufactured for that application.

If a filter did not have one or it has failed, you will have lifter rattle at cold start.

No, I'm not saying that. I'm just saying that I decided to switch back. I always know the filters will be in stock. And I'll now be hunting eBay for the deal nj_08_gts saw.

Dealership is about $7 each as I recall. I think my bill was around $15 for 2 of them.

 

That's a good point. Another point to make is that OEM is OEM for a reason...it was engineered to work with the engine. Stuff like oil filters and transmission fluids should all be OEM; that way you're guaranteed it will work properly.

 

So was your Turbo, Intake, Cams and other components.. So judging from your comment your EVO is bone stock, just the way it came from the factory including wheels and tires ?


Just as many parts, oil and filters go out for bid. Remember, lowest bidder wins..

Even Premium Manufacturers such as Hastings, make a $1.75 quick lube filter that will meet OEM Specs. That doesn't mean there $7.95 filter is the same just because Hastings makes it.

The key part to that statement is that it meets OEM specs given to them after they win the bid. The problem I have with aftermarket companies on critical components is that I can't imagine that they have the mitsu specs to design to since it is all proprietary info. Therefore they must reverse engineer or guess as to what it needs to meet.

 

Point taken and I totally understand what you're saying...guess I should have elaborated a bit...

I reached my conclusion from personal experience: I've seen a lot of guys use non-OEM products (namely transfer case fluid & some "performance" oil filters) that ended up wreaking havoc, whereas others that own the same car with similar mileage and driving habits had no issues at all while using OEM.

It could be coincidence, but I personally believe it's best to err on the side of caution and not stray from the formula with certain things. Changing ANYTHING from stock is a risk, but the use of certain OEM components helps to mitigate it, even if just a little.

Just because a low bidder wins doesn't mean the customer loses and ends up with inferior products...Bilstein, Edelbrock, & Recaro make OEM parts for some car companies and they certainly don't make inferior components.

And to answer your question, my old Galant VR4 wasn't anywhere close to stock, but all of my fluids (except brake) and oil filters were always replaced with stuff and the same goes for my '08 Lancer.

 

He doesn't have an Evo, so please give him a little bit of courtesy. It's not hard to look over to the left at the "Drives" info. You are posting in the Lancer section, after all.

Neither of us said OEM is the best part out there. But it's OEM, and that means something. For instance, if I take my car in for service with the OEM filter, I'd be pretty safe. If I take my car in with a K&N filter, a nasty dealership could easily just claim that the non-OEM filter caused the problem and deny service.

Just like they'd do with non-stock cams, intake, etc.

 

I have K&N filters for both my GTS and evo. I've always trusted K&N filters for my vehicles for many years. Plus I get a good deal buying my filters at a local shop if I buy multiple qty.

 

It is against the Law for your Dealer or OEM to deny any claims due to Brand of Product used for maintenance items ie: air and oil filters and fluids.

Also, a Dealer cannot deny Warranty for anything, it must be done by an OEM Rep.

Now, What a Dealer tries to tell you may be another thing, but it is against the Law for him to even say that a certaint maint. item will void the Warranty. Even the OEM can't do that. Magnuson-Moss Act

K&N Oil Filters are a fair product with a Micron Rating of about 17. Where they do fall short is in their Contaminent Holding Capacity.

The WIX Filters (NAPA Gold) are a great filter and do outperform the K&N. The New AMSOIL EA Series Filter is the Best Filter on the Market Exceeding 15 Micron Absolute.
