what air filter you recommend?
 

I am going to change my air filter maybe next week. What brand you guy recommend? K&N, AFE or OEM? Pros and cons?

Thanks guys

I go with OEM/Denso.

^^^^^ What he said.

Changed mine to the F-sport one. It's reusable.

Mine is non-F sport, would the F sport air filter fit in my car?

I believe the air filter box is the same, so it will fit. Just make sure you order the one for the GS and not the IS.

Here's a link for the F-sport air filter. It's sold by a Lexus dealer through eBay.

Is it any different then the stock or just washable and reusable ?

The main advantage is that it can be cleaned and reused for the life of the vehicle. Supposedly...high-flow, low-restriction air filters also marginally increase throttle response, engine performance, and fuel economy due to more air assisting with combustion, but I haven't noticed a significant difference. I didn't drive my car long enough or hard enough with the paper filter to compare. It might be slightly more noticeable when more components of the air intake system is changed.

Does Lexus service clean the Fsport filter and reinstall?

No idea. Haven't gotten to that point yet. Seems like the stock filter is changed every 30K miles, so I assume that's a good time to clean them.

Nice post. I'm at 36k mi and will need to change out my air filter. I'll just go with aftermarket drop in K&N air filter.

That's the one I bought for use in my car, fit perfectly.

I saw some comment that some people get error code about MAF cause of the oil from K&N filter, but i have it on my 12' camry and never got the error code.

Regardless it will allow dirtier air into your engine

I never got an error code, but I did experience some weird throttle response/delay issues with an oiled filter. After switching back to a dry filter and cleaning the MAF, the issues went away.

This only happens when filters are over oiled. I have an oiled cone filter and I have no issues.

I agree that over oiling would cause it. In my case, though, there were no issues until I took a long trip (~500 miles) where it literally rained the entire time. I don't know for a fact that the rain caused the oil to migrate, but that's my hypothesis.

Interesting. I am taking a ~300 mile road trip in the GS at the end of the month and it is entirely possible it will rain during that time too. I wonder if your filter experienced some soak from the rain coming thru the air inlet if it really rained at 65+mph for 7-8 hours.

I will report back if anything happens afterwards.

Oiling the filter is a pain in the ass and is not worth the hassle. The ROI just isn't there for these lifetime filters. Buy an OEM one and replace as needed.

I just like the sound of my Takeda CAI. Sounds so much nicer than stock. Don't care about any HP "gains". I think Takeda has both oiled (blue) and dry (gray) filters? I have the oiled one, only put 10K miles on it so still a ways way away from 50K cleaning.

Not the exhaust... the cold air intake. Sounds great when stepping on it, quite as can be when cruising. I have not touched the exhaust nor do I plan to. This is a quiet luxury car and I am keeping it that way lol.

They also allow more stuff/dirtier air into the engine and can trigger MAF codes or ruin sensors in some cases if you use too much oil.

Yeah, I'm thinking that's what happened.

There are two versions of the Takeda intake. I don't know if both of them are still available. It seems like they originally came with the dry filters and now come with the oiled ones.

Both are available. Only difference is the filter they put. Filter dimensions look slightly different but can probably fit each other.

yeah only difference in dimensions is the height of the filter, so all the openings, etc. will fit just fine.

Thanks. :thumbup:

No problem bud. There is a Thanks button btw! :ohyeah:

I got the k&n air filter, I change out mines every 30k. I don't reuse the old ones

Sorry - I couldn't resist...

I got the F sport filter for an IS, all the air boxes are the same for the 3.5 motors it seems.
