get the K&N unless you want to make your own heat shield. You need a heat shield though, I ran without one for awhile and could notice the power loss once the engine warmed up. The heat shield I put in my bonnie made it all go away.

Ok, that'* just like my 94 burb. What I did on that one (sorry, no pics) is to use a hole saw on the 'frying pan' to drill 3 holes on the side facing the driver'* fender, and 2 more on the passenger side to the rear of the main intake feed (flat oval). Then I used pipe fitting bulkhead connectors to give me a flange for 2" flex hose. These 5 hoses draped down to the fenderwells. This gave me 5 square inches more surface area to feed my drop-in K&N. I also installed a Summit throttle body riser at the same time.

Kindof a cool effect. It makes the intake look like a giant spider perched in the manifold. Worked like a charm.

I did my 93 K1500 in a similar fashion, but the 98 Z71 was totally different. My battery was on the driver'* side, and I had a pony keg of an airbox (much better flow) where your battery is. I ventilated and shielded the stock box on that one.

Where, can I get a throttle body riser, how much will it cost, and how much power will it give me. In the funture I look to put a better exhaust on, a CAI, a new intake manifold, and some more. These things didn't come with much baseline power, but the torque is there.

Try this for starters:

My suggestion is to call them directly, tell them your application and specify a throttle body spacer or riser.

These Trans-Dapt TBI riser plates raise the housing of the TBI unit, allowing 15 percent more airflow by the injectors for more horsepower. More power and a great price, what else could you ask for?

Be warned, getting the fuel lines to fit is a real trick. I've done two of these now, and it didn't get any easier on the second.

How much power would you say you got from it?

'feelable'. Somewhere around 10-20 hp, but I did both mods at the same time. It really becomes apparent when you're pulling a hill. You get into the power much quicker, and at a lower rpm.
