Here are some easy tips that can be done to generate improved performance for your Subaru WRX next time it appears to be running a bit sluggish. Enjoy.

CHANGE YOUR OIL

This may seem obvious, but you would be surprised at how easy it is to forget or overlook. The owner's manual for the Subaru WRX suggests changing the oil every 7,500 miles under normal driving conditions. Under normal driving conditions? Seriously, who really drives a Subaru WRX normally? The owner's manual also suggests an oil change every 3,750 if you drive ir hard. Enough said. I think we all know which of these recommendations to follow.

PROPERLY GAPPED SPARK PLUGS

The proper spacing for a 2002 - 2003 Subaru WRX is 0.028"-0.031" (0.7-0.8 mm). If you have a different year of Subaru WRX, refer to your owner's manual for proper specs. This tip may seem a bit petty, but any extra power that can be had for free is worth the time and effort.

CLEAN YOUR AIR FILTER

The manufacturer/stock Subaru WRX air filter leaves somthing to be desired, but if you don't have the extra cash to purchase an aftermarket air filter, please make sure your stock filter is clean. The more air that gets to the engine, the more power you have. Seems simple so far, right?

USE PREMIUM GASOLINE

With gas prices being what they are at present, I know that this is a hard-to-swallow tip at this time. Gas is not cheap, and premium gas can never be purchased at a price that makes it a deal, but you are driving a Subaru WRX, afterall. So, spring for the good stuff! Your Subaru WRX deserves nothing less than the best.

The next few tips are more involved; however, we are dealing with the Subaru WRX. Extra time and effort results in improved driving performance so it is well worth it.

TRY INSULATING YOUR FUEL LINES

Insulating the fuel lines of your Subaru WRX permits the temperature of your fuel to remain cooler which allows more fuel to enter the combustion chamber in addition to permitting more airflow through the chamber as well. Consequently, the more fuel and air that you have moving through the chamber of your Subaru WRX, the more power you will have to work with.

The simplest way to accomplish 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 a matter of basic physics. Less weight + more power = better performance. The less weight your WRX has to lug around, the better it will perform in every category. So, take an inventory of what has accumulated in your trunk from time to time and make sure to empty it every so often!

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