Question 1

Do I need a tune for a B58 intake?

Accepted Answer

No. Every intake on this page works on a stock car. You will get the most out of it with a tune, because the tune can use the extra airflow. Most owners buy the intake and the tune together as Stage 1.

Question 2

How much power does a B58 intake add?

Accepted Answer

Expect a small gain on its own. Burger Motorsports claims up to 8 whp for its billet intake. aFe and Eventuri claim 14 to 20 hp for their Supra intakes. Treat these as manufacturer claims, since results vary with tune, fuel and weather.

Question 3

Will a Gen 1 intake fit my Gen 2 car?

Accepted Answer

No. The Gen 1 (F-series) and Gen 2 (G-series and Supra) engines use different airboxes and inlet parts. Order by your engine, not just your model name. If you are not sure, send us your VIN.

Question 4

Is the silicone inlet pipe worth it?

Accepted Answer

It is the cheapest intake-side mod we sell. It replaces the factory plastic inlet with silicone, adds turbo sound, and is commonly bought for quicker spool. It fits Gen 1 and Gen 2 BMW, but not the Supra.

Question 5

Are these intakes legal in California?

Accepted Answer

No. None of the intakes on this page are CARB exempt, so we cannot sell them for use in California.
