oversized oil filter

What are the pros and cons of using a oversized filter on a civic engine???

nothing? :confused:

i think if you use a oversized oil filter you will increase oil capacity(but not much) and if your car has a vtec engine it will lower the oil pressure and it may cause some prblems with vtec cause it may not have enough oil pressure. if you don't have vtec don't worry about it. this is true because people who have b series vtec's can use the k series rsx type r or civic type r filter cause they are smaller and this causes the oil pressure to increase causing less fluctuation during vtec.

Didn't know they made oversized filters for Civics.

sorry to burst your bubble, but theres no "fluctuation" when it comes to VTEC. either it is engaged or its not.

very reputable people

Guys (and Gals), I've been an F-16 Fuels mech for some time now. Look at the two filters. They both have the same diameter inlet holes, and the same diameter outlet holes. As far as decreased oil pressure is concerned, the same bypass relief spring (at the top of the filter) is in both filters, which would produce equal flow pressure. One HUGE advantage to the larger filter is MORE FILTERING MEDIA, which can trap more dirt and other contaminants in the oil before getting clogged, in which case bypassing oil (ie: not filtering it). The only other difference is that the larger one has more capacity, which is good. Given that, more oil capacity equals somewhat lower oil temp (bigger filter to disperse more heat), plus more oil in which to disperse contaminants. Honda has officially "ok'd" the use of the larger filters on all new Honda Civics (I use one on my 2003 HX with 15,000mi on it).:huh:

Oh, and as far as the VTEC fluctuation.....that's a barrel of horse-shiznit!! VTEC has to do with the camshaft moving verrrrry slightly.....nothing to do with oil pressure. Don't believe all that you read (except this).:D

Okay you may know your shiz about oversized oil filters but you have no idea how VTEC works. Your camshaft doesn't move at all when VTEC engages. Oil pressure pushes a pin into the higher VTEC lobes isolating the lower rpm lobes. You camshaft doen't move and has everything to do with oil pressure. :rolleyes:

I was wrong about the operation of the VTEC system. I'm now a more informed person. Thank You.:eshooter:

Hey thanks for the insight on filters.:D
