Surbaru WRX Performance Tips

Here are some easy tips that can be done to generate a few extra ponies for your Subaru WRX next time it's feeling a little sluggish. Enjoy.

Change Your Oil
This is obvious, yet somehow, easily fogotten or overlooked. The Subaru WRX manual suggests changing the oil every 7,500 miles under normal driving conditions. Come on. Who really drives a WRX normally? The manual also suggests an oil change every 3,750 if you drive hard. Well, I guess we know which recommendation to follow.

Properly Gapped Spark Plugs
Proper spacing for an '02-'03 Subaru WRX is 0.028"-0.031" (0.7-0.8 mm). Check your manual if you have a different year WRX. This tip may seem a little anal, but any extra power that can be had for free is worth the time.

Clean Your Air Filter
The stock Subaru WRX air filter leaves something to be desired, but if you don't have the money right now to purchase and aftermarket one, please make sure your stock one is clean. The more air that gets to the engine, the more power you have. Simple right?

Use Premium Gasoline
I know gas is expensive, but you are driving a Subaru WRX. Spring for the good stuff.

The next couple tips are a little more involved but again, we are dealing with the Subaru WRX. Any extra power is worth it.

Try Insulating Your Fuel Lines
When you insulate your fuel lines, the temperature of your fuel stays cooler which can allow more fuel to enter the combustion chamber along with more air. The more fuel and air in the chamber, the more power.

The easiest way to do this is with air conditioning/refrigerator insulation which you can get from any hardware store.

Your Subaru WRX Needs to Lose Some Weight
This is basic physics. Less weight + more power = better performance. The less weight your WRX needs to pull around, the better it will porform in every category.

Well that's all I can think of for now. Stay tuned for more tips to improve your Subaru WRX.

Looking for a business idea with huge growth potential?

Have you considered grass painting?

As seen in Fortune and Inc. Magazines

I did an online search to see what is available to those wanting to start their own lawn painting business, and frankly, I was disappointed at the lack of resources. To be even more frank, I was surprised by advertisers who seem to be offering a lawn painting business in a box, for lack of a better term, and at a huge upfront investment to the entrepreneur. It is not wise to put so much money out up front at the beginning of any business.
