TRD air filter for Caldina GT-T

[Mark H]

Hi all

I've just purchased a 2001 Caldina GT-T (pics to come soon hopefully!).

I'm making a few minor mods, within the boundaries of the car's signature class warranty. I've fitted 17" alloys and Dunlop Direzzas, and have also had a new 2.5" exhaust system and installed.

I'm keen to fit a TRD air filter, but am keen to hear from anyone who has one of these (or something similar):

-What sort of difference do they make to performance? (I've had a dig on the internet and found a claimed increase in power of 5hp, which seems quite decent for something as simple as an air filter...I guess it's all about the engine's ability to breath...).

-Generally, how long do they last compared to normal $50'ish air filters? I know this will depend on the distance and conditions one travels in, but I'm interested to know whether they typically last longer than an OEM filter.

Cheers

Mark.

most aftermarket filters are cleanable. they last a lot longer before a shitty paper ones before they are filled full of crap anyway.

yes , it will make a slight difference, and youll get more whooshy sucky noises. dont expect it to be hugely noticeable tho, maybe just a slight improvement in pickup. combined with the exhaust you should notice it feeling a bit better than it was standard.

The best and cheapest way to get good gains from the intake is any type of aftermarket filter and run some ducting to the factory airbox from a cold air source.

I wouldnt bother with a TRD filter myself, they are still a paper filter so cant be cleaned. K&N are the way to go

actually they are not paper, they are fabric and do last longer.
how ever hard to say how long as it depends totally on the conditions u drive in.

for th price of a paper filter....15 bucks
you can just change them monthly......
its also proven that teh paper elements are the best filtration you can get
......till they get blocked

my 5 cents anyway :d

Thanks for the advice. I'd undoubtedly consider other aftermarket air filters such as K & N, especially if they are washable. However, I have to use Toyota approved parts to keep my warranty valid, hence the reference to TRD airfilters.

Filtration between a paper element, and a properly cleaned+oiled k+n is pretty marginal I thought? And with the K+N you get better flow surely?

Less filtration = less restriction = better flow
Hence K&N should have better flow than paper

Look at a lot of K&N filters and you can just about see through them. Run one for a few thousand kms and have a look at the intake piping after it and see what you reckon. Have used a few cheaper K&N style oiled filters and have had varied results

you would cry if you saw how much atually gets though a k&n
really the only thing that sports filters stop getting into your engine is birds small children and the ocasional skank that gets to close :d
