Hello all:
It is about time to change the oil/filter on my 4C. For those unfamiliar it runs a fairly crazy little boosted 4 cylinder that is 1.7L but makes over 300 HP in slightly modified guise such as I am in. I run either M1 or Castrol 0W-40. For the longest time the only filter available was the OEM Mann canister filter. It was/is an expensive POS and nothing is special about it aside from a high bypass pressure of 2.5 bar (35 psi). See https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/4156392/1. The pictures seem to be dead, you can find them here: https://www.4c-forums.com/16-engine-technical/32425-4c-oil-filter-problems.html.
Well, in 3 years time there are other options. Apparently the factory filter is now a Mopar unit which is a little bit sacrilegious for an Italian car but such is the global economy in which we now live. It is likely a rebadge of the Mann filter but could be something different entirely. Not much is known about it.
A number of other filters are now known to fit. Specifically, Royal Purple, M1 EP, and both a normal Wix and a Wix XP also fit. I wish that an Ultra fit this application but alas it isn't to be. Problem is that all of those filters to my knowledge use the usual 1 bar bypass pressure which is much lower than the OEM filter. Purolator makes a filter that will likely fit that uses a higher bypass pressure but it is my understanding that the Purolators have not been so hot as of late.
So, my question to the experts here are should I just bite the bullet and pay $25 for a crappy OEM filter that has a pretty high bypass pressure spec, run a better spec filter (M1, Royal Purple) that uses a lower bypass pressure, or take a chance on a Purolator that has a somewhat higher but still not OEM level bypass pressure spec? What would you do if this were your car?
Also, if anyone knows of another filter that has a fitment for this weird little car that would be better I would love to hear it. Let me know.
Thank you to everyone in advance.
