Hondata Intake Manifold Gasket DIY Install

1997 Acura Integra GSR engine (B18C1)
Difficulty on a scale of 1-10: 2.5
Time required: 30-45 minutes
Tools required: 3/8" Ratchet, 12mm socket, 3/8" extension, 12mm wrench, pliers, & gasket scraper

First, lets examine our lovely new Hondata Intake Manifold Spacer Gasket. This places the intake manifold further away from the head, aiding in cooler air intake temperatures. Hondata claims gains of 3%, on a 170 horsepower Acura Integra GSR motor we're looking at nearly 5 horsepower. While it won't turn your car into a rocket, it's surely worth the $50 pricetag.

Let's unwrap it from the packaging and check out the installation instructions.

Step 1: Allow sufficient time for the car to cool down. You don't want to burn yourself on scorching hot engine parts. Let's take a look at our test subject. A 1992 Honda Civic CX hatchback with a 1997 Acura Integra GSR engine swap.

Step 2: Loosen the two bolts connecting the air intake to the throttle body. Move the intake out of the way. No need to remove it from the engine bay, however.

Step 3: Remove the ten 12mm nuts and bolts holding the intake manifold to the head (There will be four bolts, and six nuts). Luckily, our Edelbrock intake manifold does not have the intake manifold bracket that the stock GSR intake manifold has. If you still have your stock intake, you will need to remove the intake manifold bracket bolts located on the lower backside of the engine.

Step 4:Place shop rags below the intake manifold to catch the coolant that flows out once the intake manifold is removed. You will need a few towels, one will not cut it.

Step 5: Disconnect the little rubber hose under the VTEC solenoid using a pliers to open the clamp. This will allow you to move the intake manifold more freely.

Step 6: You can now slide the intake manifold away from the head and off of the head studs.

Step 7: Using your handy gasket scraper, remove the old intake manifold gasket.

Step 8: You can now place the new Hondata gasket into place. The large coolant hole will be closest to the passenger bottom. There is only one way the gasket will fit so you don't have to worry about placing it incorrectly.

Step 9: Install is the same as removal. You will need to refill the coolant that had dripped out earlier. Also, make sure to re-tighten the nuts and bolts after 200 miles of driving.

Step 10: You are now finished with this install. Go out and have some fun.
