BBK intake spacers fit between the upper and lower intakes to create a heat flow barrier, keeping the air in the upper intake cooler and denser while allowing the use of taller valve covers by raising the intake's height.

BBK Phenolic Manifold Spacers Have Also Become A Popular Way Of Increasing Manifold To Valve Cover Clearance To Accommodate Popular Bolt-Ons Such As Performance Rocker Arm Covers
Will this spacer raise the intake too much to fit under stock hood? I have a early explorer intake and was worried with it raising the upper that it might be too high for the stock hood. Asked by Jonathan J.from Decatur | Comment10
Best Answer: Jonathan,
This spacer kit will not cause an interference with your stock hood, however, if you go any larger than 3/8" you might run into some clearance issues. Answered by Tim R.from Hewitt | Comment10
Just so you know, the kit comes with two long bolts and two short bolts, which replace the two short bolts on the ears of passenger side of intake and the long ones go on the ends of the tallest part of both ends of the intake, you will have to reuse your existing two long bolts from an old intake to go in the center two holes. I wanted to say that in case you have no bolts right now and are expecting this kit to provide you with all six. It's too easy to just hardware store it for the two bolts you need though so no big deal if you don't have it.
I have an explorer intake, later model with EGR in center, so this intake spacer fits fine. I also have a 1995 and this spacer just barely clears my stock hood. I have less than a millimeter clearance and if you press firmly down on center of my hood it does contact the highest point on the intake which is the front most bolt. You will have to remove the hood liner on 94-95's. Stock strut tower brace will not clear, if you are handy with a welder the stock brace is 1" steel tubing and easy to customize.
On 94-95 models you will need to adjust your EGR tube if you still run it. Mine was short by same distance as the spacer so I went and purchased a 1/2" section of steel tubing and just welded up a spacer inline with the tubing, this also gave me time to customize the bend of it so it was a lot easier to get on and off without forcing it like I used to have to with aftermarket headers. Alternatively you may be able to get the Edelbrock 1" EGR spacer sold by LRS, it might put you the other way and you have to remove some of the tubing though, I don't know for sure. Another alternative would be possibly cutting the EGR tube, get a section of tubing with 1/2" inside diameter and then use that as a spacer and clamp it on to seal it. In emissions states that might be a red flag though so do your homework.
This spacer gave me much needed clearance for my valve covers, and makes a much easier time with small things such as trying to test fuel injectors with noid lights, because now you can just barely reach under the driver side plenum and reach an injector harness whereas stock you would have to be super tiny hands toddler sized.
Be careful with brittle emissions vacuum hoses, they need to be brought up to meet the now higher vacuum ports of your intake and may have added stress placed on them and crack....mine did during install.
Seemingly insignificant things to think about when using a spacer, such as torquing down your upper plenum. The spacer is a slightly compressible material and if you torque it too much you can crack your upper plenum, especially the two weak ears of the intake...I did! I would do maybe 10 ft lbs to start, at most maybe 14 or so. I went right for around 20 foot lbs like I always have before and heard a nice loud crack as the front ear by the number 1 runner broke. Luckily explorer intakes are so cheap and plentiful, I just have to port another upper all over again but oh well, its fun and good practice.
Great quality product, great price, thank you LRS!
Yes, I would recommend this item to a friend!

Made my new style injectors with the adaptors fit under the intake. The stock hood on my 95 mustang was able to close with this spacer.
