    Hi i just joined this site....

    I need some help. I am looking at either getting a throttle body spacer and cold air intake, or headers. can someone give me an opinion what would be a better choice? Also, Does anyone know about the hp gains and sound differences with the JBA headers im looking at? thanx

    welcome!! skip the throttle body spacer man..................all it does is whistle and lighten your pocket. depending on the year of your truck..........if its got the 3.4 v6....you can do the deckplate mod instead of the intake...............if you have the 2nd generation tacoma....yank the secondary air filter out and get a good drop in filter.............................all cheaper than a cai.....and will yield the same, or better results. go with the headers tho.......small, but good gain. not sure which jba's you are looking at, but they should be ok....tho i dont know the specifics of them.

    Removing the secondary air filter has been proven to do nothing.

    I would advise getting headers all the way. I just put on a set of Doug Thorley Long Tubes earlier this month, and I love them. Great sound, more torque, more horsepower.

    I don't know much about the JBAs though.

    Love the sound. And truck pulls nice above 3000 RPM. I havee the JBA's, not too happy with them, but thats just mine, some others had no issues. Will be ordering my DTLT's next week. Oh and if you feel like wasting cash on a TB Spacer, I can save you some and give my street performance TBS for $45.00 shipped:D Apparently did not fit w/current intake set up, so I finally had an excuse to get rid of it. No more whistle LOL,,,

    wat?
    so leaving in a thick cotton-ish filter in the way of air getting to the engine is the same as taking it out? i dont think so. there's not as big of a gain on the v6, but ppl w/ the 4cyl have seen better results

    Look at the surface area of the filter in relation to the cfm of air being taken into the engine. The charcoal filter isnt felt by the engine. Gadget has found no gains on a dyno with the filter removed, neither have I.

    i think we should agree to disagree on the secondary filter. as i had said before....on my 06 with the 4.0.................i felt that my truck idled a bit better, and thats about it. lots of people have felt significant increases on the 4cyl. gadget tested the filter and didnt find anything with it. lets look at it like this...............if you feel that it does something,cool.....if you feel that it doesnt...cool again. if it isnt gonna hurt to take it out or leave it in either way....what does it matter really? if you wanna take it out...do so......if you wanna leave it in.........feel free. simple.;)

    No. A 2.7 wasnt tested. And it may very well work on that engine, for all I know. A dyno cant really check for Throtle response, but now I find Im going into the same argument that I had with Airaid when I dynoed their spacers. Here we go.........By saying "thortle response has improved", Im assumeing you mean the engine feels more responsive when driveing under part throtle conditions. That being the case, the throtle "Buterfly" has WAY more constriction on the engine. It creats most of the pumping loss in the engine, as the pistons have to pull against it on their way down their stroke. Anytime the engine is not under WOT, the throtle body is creating the most resistance in the intake tract. Also, the "improved throtle response" could simply be that the engine is more run in. I have seen MANY tests that, when ALL the filters are removed, the engine actually makes LESS h.p. $0.02

    x2 the throttle body spacer does sound cool but all it did was set me back about $120 bucks no gains in hp at all..... i did the dec plate mod headers and exhaust and it did a good bit for me and sounds great
