Air filter

    I am planning to order an OEM replacement air filter for my 1989 Toyota Celica GT-S Convertible. I am confused. 4 Wheel Online has a lot of good options, a K&N and an AFE replacement air filter. What should I go for?

    Don't expect a massive jump in power, but if a K&N or AFE is in the budget then go for it. Take care of them and you'll never need to replace them.

    I've had good results with the K&N panel in the stock air box. Always used the correct cleaner and red spray oil a couple times a year.
    Probably no noticeable performance gain, but I never worry about dirt getting in...

    not to hijack, but would a short ram get any more power than a drop in on a gts?

    A short ram system will only ever be any good if you eliminate hot air getting in.Me personally on all sorts of NA/FI cars I've never seen an aftermarket cone filter or that type that has actually been a lot of good for performance.Stock airbox with a free flow panel filter and an extra cold feed from the outside is in my opinion the best option.I did the same for my BEAMS engine conversion;I drilled an extra hole in the base of the stock 'box,airsealed a proper piece of induction pipe through from the box to the outside of the car and i can categorically state that inlet air temps will be hugely improved over a big cone filter with or without a short ram pipe,unless the cone is encased from underbonnet engine temps with a dedicated cold air feed.
