Title: Air filters - any difference between makes?
Post by: Mr Lazy on July 28, 2020, 15:00
I've searched this in the forum but can't find anything conclusive. I've noticed that Euro Car Parts are currently selling a Fram air filter for just £3.39. At that price it would seem rude not to buy it. Is it going to be rubbish though? It got me wondering if there is any difference between makers of disposable air filters (so not the likes of K&N). Do any makes have more than one suitable model in their range? I've looked at one or two reviews on YouTube etc and to some extent they contradict each other. What are your thoughts on this? Maybe I'm over-thinking the whole thing.

Thanks both. As you have said previously then Ardent, these cars are certainly cheap to maintain!

Same logic as spark plugs and oil;
Cheap and often is better than expensive and rarely.

I am running a basic cone induction kit behind the battery, if still running the stock airbox just use a standard paper filter - think the airbox is the same size as the 2zz airbox which can support 50bhp more than the 1zz so will flow fine.

Apparently the stock air box strangles the 2ZZ.

Another case, I suggest of making your choice and paying your money:

Love him or hate him Scotty maybe makes a valid point about oil impregnated air filters and the MAF

Ah yes, I watched the first one before starting this post. The trouble is that it isn't entirely consistent with another review that I saw. The point about the oil impregnated filters is one reason why I'm avoiding them, as well as the fact that they are very expensive!

I've definitely used a fair bit of oil-based. Filters and, when done right, your MAF is never dirtier than normal. 
The problem is that a lot/most of people over-oil them. And it's very difficult to know when enough is enough. 

All easily avoided by just using paper :)

I've been using a K&N oiled filter for the past 5-6 years without issue, but whether or not it gives me any more performance over an plain paper filter I wouldn't know.

I doubt even changing back to the paper one, I would notice anything.

TBH I think I bought it to save money and time, but by the time you get it out, clean it, oil it and leave it to dry, you could have swapped a paper filter much quicker.

No - no difference.

For the Roadster, yes - see page 263 of the owner's manual 8)
(Oh! there I go again quoting the manual) ;)

I've always used Wix Paper Filters, cheap as chips on Ebay and never let me down
