Yes it's the age old question Do phenolic (or any insulating) intake manifold spacers really work? Do they actually cool the intake change and make power? I vote 'No'. An intake manifold gasket is a flexible, fitted part of a car engine that helps prevent air from leaking out during fuel combustion and helps regulate chamber temperature. But no plastic spacers on a stock intake with the crossover open - it'll melt them IMHO. but why do all modifications have to be backed up with Power Gains of a mass amount? is it that big of a deal, if it feels better to a person? making them happier in the long run. Some car enthusiasts are skeptical about throttle body spacers, since they're not offered by car manufacturers. If so, I have seen on my 59 Eldos that the hoses can get chapped running along the valley pan if not clamped down in the middle, and could - if not replaced - get a pin hole, after work on the heads or intake. This spacer seems to offer some mid-range boost when a carburetor and manifold combination are primarily designed for very high engine speeds. If they did work it would only be in a very limited RPM band - probably in the upper extreme RPM range where things got to moving so fast that. So they polished the inside of the intake. Spacers don't magically create power. However there are. the dowel was there to locate the intake manifold so that where the dissy goes thru it would be square to the pilot hole in the block where the dissy drives the oil pump. Rusty Roar Enterprises Earn Money With Blogging. The intake works well if you have headers or a cam swap. (just my luck) I'm poor so I can't afford anything else right now. Ram charge wave tuning is stronger resulting in more mid-range torque (6lbft) and top-end power (3hp). Our plate is a bolt on part to eliminate the wall and increase air flow. We Test Intake Manifolds and Carburetors on our 440 Stroker in Search of Ultimate Power It is really hard to beat the simplicity of a merge spacer; they almost always seem to be the way to go. Of course mine engine isn't very "stock" (5. Hello, I have a 1997 Ford Expedition 5. every forum i have been apart of requires people selling products to register as a vendor and pay to do such. Adding an open spacer between the intake manifold and a carb allows any particular cylinder to see all four barrels of carburetion. I am only flowing the intake manifold by itself, so in reality, by the time you figure you strap on the intake system, throttle body, and put it to a head, the 20% gain I mention flowing the intake alone may only be something like 5% (this is theoretical number) when you figure in everything else if I were to flow the whole intake system. I bought the K&N co-polymer cold air intake and cut 7/8" off where it sleeves into the throttle body with a rubber connecting clamp-able mating to the aluminum of the throttle body with a Helix Tower spacer behind the throttle body its self. they're not all things to all people. i would be willing to try one out. Over 250 000 000 carburetors have been manufactured over the years for everything from Henry Ford's original Model A to the baddest factory muscle cars. I had a fuel boiling problem before going to the restricted gaskets on a single 4 barrel manifold and the phenolic spacer remedied that problem. The rear bank spacer (once modified) will only match up to the corresponding rear bank. Small plenums = lower RPM power curves (below 6,500 - 8,000 RPM) and greater lower RPM response (velocity and mixture), for quicker power and torque curves. But do they clear the block without spacers? 5.
