Tune up Time? Do it Right!

For years, we’ve been preaching the virtues of routine maintenance. The reliability, performance, and economy to be gained from a finely tuned car can provide miles of smiles, and, with today’s prices at the pump, it pays to “stay in tune” with the needs of your car. Surveys consistently show that there are still a “few” of us who like the thrill of living on the edge when it comes to routine maintenance.

The potential negative effects on safety, emissions, vehicle performance and dependability increases greatly as components age and fluids degrade. Difficult cold starts, poor mileage, slower acceleration and increased wear on internal components can detract seriously from the superior reliability and longevity of our beloved Volvos. Dedicating one weekend a year to replacing worn tune-up parts will not only put you more in touch with your car and its needs, but the rewards of fixing something yourself can last as long as your Volvo.

The first step to a well-balanced relationship between car and driver is a tune-up kit from ipd. Utilizing original equipment Bosch components where applicable for the best in quality and value, our tune-up kits offer the ideal platform for efficient performance. For those considering a complete service makeover, our 60,000-mile extended service kits offer the necessary components for a complete service of the engine and drivetrain on your Volvo. All of the parts in our kits are OEM quality for the best in performance and fitment. For more information on ipd tune-up kits, their applications, or additional maintenance advice, give us a call.

Spark Blowout Or Is It My Birthday?

By: Rob Arnold

Somehow in this day of skepticism and disbelief we have allowed a sneaky little myth to arise and take hold of a position in the ranks of car enthusiast vernacular. Spark Blowout. I’m not sure what this even means but I hear it all the time. I think the people who use it are talking about the air flow from a turbo blowing out the ignition spark like it was a birthday candle. If that is the case, it’s not quite accurate but I can see where the misnomer came from. Firstly, electricity cannot be ‘blown out’ in an engine because at the moment of combustion the air and fuel in the cylinder isn’t moving very quickly when compared to when it enters the cylinder via the intake valve. Once the valve closes and the piston heads up toward top dead center the air/fuel mixture is forced into a tightly closed, highly compressed area and there’s not much blowing happening. Shortly thereafter the spark plug passes the spark across its electrodes and Kablam, combustion. The term most likely arose from the experience of higher than stock turbo pressures attributing to ignition misfire. This is in fact reality but not from a ‘blow out’ spark event. The result of ignition misfire is from the higher combustion pressure due to the higher turbo pressure, which packs more molecules of fuel and air into the same space making the ionization voltage of the spark plug rise to a level that the coil, wires, cap, rotor cannot support. Recall that ionization voltage is the initial voltage necessary to start the spark jump across the spark plug terminals. Once the gap is jumped and electricity begins to flow the voltage needed is now lower and this voltage is referred to as burn voltage. So, how to combat ignition misfires due to high cylinder pressure? First make sure your cars ignition system is in good shape. Replace the cap, rotor, plugs, and plug wires if they are old or worn out. The best defence against misfires is to insure that all components or your ignitions system are in great shape. You’ll find that these performance upgrades will make the difference between a high performance car and a reliable high performance car.
