Are Throttle Body Spacers worth it?

[mel1310]

Ive had some friends say that i need to get throttle body spacers to go along with my cold air intake. Is that something that i should get? I was told that i would get some better hp and better mpg. My questions are: is it worth getting? and, would i see a noticable increase in those two things (hp and mpg)?

[firecrew]

No No No No No

[mel1310]

why is that?

As one of the other members put it... "they make great paper weights" Not worth the money. No noticable power or mpg gains. spend your money else where.

ok, so ill spend my money on something else for the truck

PowerAid Throttle Body Spacers 07-08 Toyota Tundra 5.7L

Air Raid Intake W/ Spacer?..

I put one on my 2000 tundra and it didn't do anything for the power or gas mileage. I took it off to allow the KnN intake to fit anyway. Like Hawaii says "Paper weight".

Adding less than 4" to a throttle body will not do anything unless it involves the actual runner length on the manifold...

if I use the spacers as a paper weight, then maybe I'll get the tornado!!!!! LOL!

i tried a helix throttle body spacer recently (only cuz i found it for so cheap) and less than an hour after i put it on, my check engine light came on. once I took the spacer out, disconnected and reconnected the battery, all is well again.

(im using a k&n cai too)

paperweight is right!

The only thing I have heard of them working on is the older trucks with tbi.

Luv your bottom line.....As they say Where's the Love...

Well they say there's one in every crowd.So here it is.

Take any type of hot rod engine.What makes them have more horse power???????? More air in and more air out.the faster it comes in and the faster it goes out produces more HP.

Started off a long time ago.Volicity stacks,red ram on the dodges.hemi charger,hilborn ram tube injection,carb spacers,turbo chargers,supercharger.

You mean after all these years of trial and error by the best engine builders in the business that none of this helps?????????????????????Look at the pro stock cars with there 12 inch tall ram induction running twin 1050.At 10 grand those intakes will suck the feathers ofen Gramp's turkey at 100 yards.

I have to disagree.All these engine builders cannot be wrong,the more air in,the faster you get that air in and the faster it gets out the tail pipes the more power and toruqe you get.

Call Lee Hurley or Chuck McBryer at Hesco and ask them what a CNC billit aluminun 2"TBS did to their 4.7 stroker motor.That was dyno proven and they have the charts to prove it.Don't quote this paper weight business unless you really know the source.My prototype TBS gave me 10 more dyno proven HP.

I won't give my name out on this channel,but if you chose to call them and Bennie answers the phone tell him it's coming from the guy that lived in Louisville,Ky,had his offroad TJ at Moab Offroad and they flew the company airplane from Birmingham,Al to L'Ville to help in the startup process.

I don't know much about this 5.7 engine we have.Maybe a TBS is no good,but then on the other hand if it increases air flow velocity then why would it not be a good thing.If improving air flow to this engine does not help it then why is all this talk about CAI,and loud pipes coming out the rear One thing I do know if this ECU cannot be broken into as some say and it is set in it's OEM mode then increasing air flow will make it run lean at a higher rpm and may do harm to your engine.

Someone running improved air flow needs to makes about a mile long bonzi run,shut they engine off so as not to corrupt the electrodes and do a plug read.White means too hot,light brown haze right on the money,black,too rich.

Well I'm off my soap box and looking forward to my 8/71 Weiand SC to,ahhhhhh,all I know,INCREASE AIRFLOW.Reason behind a 8/71 over the 6/71 is moving a greater volume of air at the same rpms.

not worth it

Burnout, you got to look at the configuration of the fuel system. It may be true that installing a spacer to the types of fuel systems you're talking about may have shown some increases in power but, the systems you're talking about are injecting fuel closer toward the throttle body. Like all carburetors, fuel tends to atomize better given more time. That's why spacers have proven benefits. But modern fuel injection directs fuel directly on a hot intake valve. This has 2 adverse effects, one being a cooler valve and the other being a very precisely atomized measure of fuel.

Cold air Intakes are different from what you're talking about too. CAIs' in principle tries to draw air from a cooler area resulting in a denser air charge. Denser air results in an increase in power.
