I recently purchased a set of 1/2" aluminum intake manifold spacers from board member micktroup, and installed them today. I installed them on my 1987 sport coupe with 2.8L engine and 700r4 combo, I have the factory original intake manifold with the upper/middle/lower plenum design. There have been no mods done to the engine itself, although I do have K&N air filters, a full MSD ignition with box, coil, 8mm wires, cap and rotor, a Hypertech thermo master chip and thermostat which run my engine at 160 degrees.
They were easy to install, as advertised, but they do cause my BMR strut tower brace to rub some on the throttle body, which may lead to me removing the brace or increasing the height of the brace with a washer or two.
I did not do any other mods when I installed them, though I was tempted to do the throttle body bypass mod while I was in there. Although it should probably be alright to do so here in the always hot west Texas desert, I chose not to so I wouldn't corrupt any testing of the spacers themselves.
After installation, the car seemed to start a little easier than normal. I started off with a liesurely drive down a main-ish street on my way to get a haircut here in El Paso, and the car seemed to work much less hard than it did before to accellerate up to and then maintain the 45 mph cruising speed.
After my haircut, I took it onto the highway, and noticed an immediate improvement in accelleration up to highway speeds (60 mph) even going uphill on the onramp. There was additional noise from the engine, but it wasn't a bad noise, you could just hear "more engine" like you would if you gutted the airbox or installed a low-end catback system or muffler.
The car *really* seems to like the parts. Once I got up to 60, she wanted a little more, so I increased to 70 mph without any hesitation or having to mash the pedal down so my 700r4 would shift into third.
I won't tell you that this addition will plant your butt in the seat or knock your head back during accelleration. I'm also not smart enough about engines yet to tell you whether or not the spacers added power or moved the power band down to a more accessible level. I will say that after an hour-long shakedown cruise that there is a clearly perceivable increase in accellerative power than there was before the installation when used for normal day-to-day street and highway driving.
In closing, if you are looking to either have access to your stock or mildly modded 60 degree v6 engine's power earlier, or increase your low end power (whichever is more correct to say) for cruising or daily driving, message micktroup, buy these and install them.
