The best approach in our opinion to making POWER in any motor is to make sure the motor has the best chance to breath and take in all the air it can…. More air + More Fuel = MORE POWER…it’s that simple.
With that strategy in mind, we look at the most affordable and “Best Bang for buck” options, while also understanding if this question is being asked, usually the customer is fresh or new to the car seen or modding (And we welcome you!! 😉
So to get started, we practice what we preach, as all of our parts listed on our online store ( http://halferlandperformance-com.3dcartstores.com/ ) focus directly on this model. The first place to look will be Intake Manifold, and here is where Spacers come into play. A lot of guys get fooled into think Spacers (Manifold and Throttle body) will make power…THAT’S WRONG! Spacer do effect the motor, but not in the way most think. Spacers, simply put, are just extensions of the intake plenums/runners…the longer the runner the more Torque a motor makes down low, the shorter the runner/plenum usually means the motor will have more top end. So really in the end spacers are only simply shifting or moving the power band around, with it usually gaining about 4-5 torque down low in the 2500-4500rpm range…but when power is added down low, it takes that power from somewhere else, and that “somewhere else” is usually always your TOP END POWER. So essentially all it’s doing is moving the power from your top end, down lower in the power band, NOT gaining any power and actually LOSING Power up top!! This also holds true with TB spacers, but that shift in power is EVEN LESS then IM spacers, making TB spacer completely worthless….ultimate Snake Oil!!!
Further more, the Spacers you see some companies offer are cut in half (half the size) as the OEM full size spacer would require your hood to be spaced up or the hood wouldn’t close. To get past this, those companies cut the spacers in half, essentially make that part only half effective as it should be. So in the end, they get two parts to sell for the price of (1) and you get half the gains……which is next to nothing. Full size spacers will move the power band and you’ll see 4-5tq gains down low (again losing power up top), Now cut that in half and that nets you a whopping 1-2.5 tq gains!!!) . For the cost, time, effort, etc….it’s simply not worth the effort or your money. Again, all of our parts through our store focus on parts that have been PROVEN to make a difference and GAIN power, not simply shift it around (PnP IM 8-15whp Gains, PnP Stage 3 Venturi TB 5-12whp gains, PnP Runners 5-15whp Gains).
In the end, it’s always our customers vehicles and their decisions as to what they spend their money on. If we had a say in there build, you will NEVER find any spacers on our cars, whether TB or Manifold spacers. This may seem as a harsh or very direct way to address this topic, but in the end we have seen far too many of our customer fall for these advertising tricks and “Snake oil” products. Stick to what has been proven to make power, not what seems to be the easy way out…..and ultimately, many of our proven parts are not too much more in cost the those Snake oil Spacers. 😉
