turnerjr Posted September 19, 2023 Share Posted September 19, 2023 Hi all. Is anyone using anything other than oem air filters in their oem air box? My supra is due a service soon and Ive always used the genuine toyota ones. I was just wondering if anyone has used anything else which is better? I remember TRD doing one but it looks like they have been discontinued now. HKS do one but after doing some research people seem to think HKS air filters arent very good.

TuneR Posted September 20, 2023 Share Posted September 20, 2023 I've a K&N re-useable OEM replacement filter in mine, iirc the HKS i had in another car started disintegrating after it got old. Think it was a type of plastic that turned into fine dust so i'd never buy one. Quote Link to comment Share on other sites More sharing options...

I have used the Blue Print filter for the last few years, gets changed every 3 years of roughly every 500 miles. If you want, I can go check the part number from my next years fit that is sitting on my garage shelf ready to go. Quote Link to comment Share on other sites More sharing options...
turnerjr Posted September 20, 2023 Author Share Posted September 20, 2023 Good shout on the K&N, I never considered them. Thanks for the info rider, I already use an oem one which is changed yearly, I just wondered if there were any performance gains etc to be had by switching to something like a K&N, blitz, HKS etc, or whether their claims for better airflow etc are just nonsense Quote Link to comment Share on other sites More sharing options...
Dnk Posted September 21, 2023 Share Posted September 21, 2023 Do Apexi do one ? Supposed to be one of the better filters out there Quote Link to comment Share on other sites More sharing options...
rider Posted September 21, 2023 Share Posted September 21, 2023 I have a K&N filter on one of my cars and its a pain of a clean up and re oiling process with of course, uses very expensive proprietary pink oil. I wouldn't go there again, it was just that they had a thin filter required with limited over carb head room between the engine and closed bonnet. I recall reading in the distance past that if you managed to gain 5hp from a free flow air filter you were doing well so, although every little helps, its not going to be a game changer. Worth a read: https://www.carsdirect.com/car-maintenance/pros-and-cons-of-a-high-flow-air-filter Basically a performance filter offers less resistance to flow so it lets more air and along with that shit into the engine (that the OEM paper element one would absorb). It is as with most things, a dirty air filter will impede air flow and available hp more than a performance air filter will enhance flow so if the air filter is changed regularly, ahead of being restricted by dirt then that will probably be the best all round deal. Lets not forget all those cheap cone filters people fitted back in the 90's where the foam degraded leaving the engine to suck through a lot of abrasive powder.
