Lot of folks think that this plug is better than that plug the truth is spark is spark unless you switch to msd systems or do major changes like that as long as the coil can lite the fuel mixture your truck will run fine(like e stock)
a higher out put coil will help more than anything coupled with a msd(multi spark discharge) system (noticeable gains in torque at rpms up to 3000 and no misfires at high rpms)
but when you go messing around with things that you don't really understand like heat ranges AND TIMING =YOUR GONNA CHANGE THE HEAD GASKET \
if you can run your plug gaps wider it results in a bigger flame and more complete lighting of the a/f mixture but without upgrading your coil then the wires then the cap and rotor (just like everything else you do to trick your truck )(IE lifting-bigger tires -lower gears -stronger axles-stronger birfields-adding CV joints to your driveshafts -longer shocks- bigger brakes -ect ect ect ect it never stops does it guys ) roflmao
all I'm saying is unless your gonna kick down with about 300.00 plus bucks and time or engine repairs when things aren't right better just leave it alone
u can try this one up grade safely buy a high out put coil and open up you plug gaps to around .050 -.060 put the stock plugs in it and watch how much you gain with that-my guess is mostly you change plugs more often and only gain a tiny bit of torque at idle in low gear and maybe a little bit on the top end (it wont miss at high speed or until the valves float) but when you turn a 22r or re at high speed your motor wont last too long and it wont matter anyway cause you'll blow it up
bottom line is the is no cheap or free way to get more power other than use good tune up parts set every thing to Toyota specs make sure all the vacuum lines are routed correctly (as on the under hood label) set the valves at .008 intake and .012 exhaust
make sure the engine temp is at least 180f and not over 200f
use good oil and keep it clean change your air filter
make sure that the cold air tubes are in place from the air cleaner to the grille(pre-heated air robbs power) make sure that your egr valve is working properly or the Head gasket WILL FAIL between cylinders 3 @4
make sure the exhaust is not plugged and get rid of that factory (restrictive)muffler(use a magna flow or dyna max)
don't use anything over 2" on the exhaust (it needs some back pressure)
and just concentrate on stuff like this and you will have many years of reliable peak performance and decent milage depending on you final gear ratio(tire size and gear ratio in the pumpkins)
all these things are a must even with a beefed up motor and if you cant do all of this first your wasting time and money that you probably don't have to begin with
if money is no object and you have the basics down already get a LC engineering motor and thrash it and have fun
trust me i have owned over 40 Toyota trucks myself and built probably twice that many engines on top of my own and unless your gonna spend big bucks and have another daily driver stick to what you have now
and save your money for retirement or a trip to the Bahama's because when your done playing with this and adjusting that its gonna just cost you more in the long run- and you could have more fun doing other things rather than dumping it in your truck trying to get just a little more out of it with out going all out
i guess what I'm trying to say is if it don't miss and it starts every time and get OK milage and don't run hot ,don't mess with it and go have fun on the trail man it will take you there and back just fine the way it is and you will be able to afford the gas it takes to do it all
oh one more thing a 3 core radiator is also a smart upgrade that will keep you going longer and i can get them for about 150.00 all day(that includes my commission lol)
ant way happy trails
