k & n air intake on the 4 banger 07 taco, good idea or not?

Hey yall, I had heard that the air intakes for the 4 cylinder are just a pain and bad for the engine, is that true? I saw that there is a 7 hp increase on the dyno from the k & n website but I would like to know from you other taco owners If there is another intake you might suggest please do so, Thanks so much for your time can't wait to hear back!!!

plenty of 2.7L people have either drop in filters or full intake kits. there's also the DIY secondary air filter thread thats stickied a the top of this section to remove the charcoal filter for more airflow and apparently a few more mpg. but if u live in cali, its not recommended b/c of emissions

I would say that you can probably get a good gain from the intake, but I have had poor experiences with K&N in the past. They tend to leave a residue in your intake tube.

I am trying out a AFE drop-in right now on my 2.7L. It has been in there for about 1200 miles now, and it has proven itself in economy and power increase. I plan on taking the intake apart today to see if there is any residue left behind.

I just installed the K&N a couple of weeks ago and I really like it. I have the 63 series. It was an easy install, and while I do live in Los Angeles I know I will need to reinstall the stock air flow in 5 years when it's time for a smog certification (or maybe K&N [a Calif. company] will have the certification by then). It seems to me the Taco is more responsive.

He was right, my truck accelerates faster after 2500 rpm and my mpg's went up. I have an extra air filter box in case I need to take the truck in for service at the dealer. I didn't have residue at 600 miles but I'll check today also since I've added another 600 since then. I probably wont bother with a cai anymore, probably spend my money on an exhaust.
I am in the same boat. I am not going to bother with the CAI for now. Exhaust? - maybe next year.

I did take my intake apart. 4,000 miles and no residue on the intake tube or housing. I also carry an extra filter for "dealer visits".

Please refer to the "Magnuson Moss Act"... No, they cannot deny your warranty without proof that the aftermarket product caused the damage that is claimed under the warranty.

don't waste your time with a K&N or similar oiled cotton element filters. yeah, they're fancy and neat, and you "feel" some extra horses, but check out dyno results. typically gains are seen in the top end opposed to low and mid range where real world street performance comes into play. Occasionally, you'll see a few hp's in the low end. But, imo, it is not worth it considering you take a higher risk of crap getting by with oiled filters. read how many MAF sensor failures occur with K&N's and how many don't fail with OEM filters.

If you're a dragster go for it, but if you want real world useable power and longevity go for headers, exhaust, fuel mapping. Be careful of the hype
