APR Ignition Coils are designed to be a direct plug-and-play upgrade to factory coils, and provide greater energy output, ensuring a stronger and more consistent spark. The commonplace replacement of factory ignition coils with those taken from higher output Audi RS models, such as the 2.5T, is popularly believed to provide greater energy output. However, testing proves that they are no more powerful than the factory coils that are found on 1.8T and 2.0T engines. APR Ignition Coils increase energy output by 10%. They are a direct upgrade or replacement, and come with the coveted red housing made popular by the Audi R8!
Any stage they will provide more spark energy, less chances to misfire, have a plug blown out, etc. If you're not ready to buy now, wait for a factory to go before picking up a set.
Oh please! Do you really think that we are that gullible - some of us are Engineers by profession. Are you claiming any difference in output power of the engine? No.
The extra energy has to be supplied by the ECU output circuits adding additional load to the ECU output electronics and reducing the life of the ECU. Lower impedance and/or more inductive reactance can increase the probability of ECU output stage failure, due to higher currents and/or higher “kickback” voltage. The factory coils are carefully electrically matched to the ECU.
The higher discharge voltage at the spark plug reduces the life of the plug and reduces the MTBF of the plug and increases the risk of insulator breakdown - particles of the ceramic insulator can cause severe cylinder damage.
VW have a dedicated team improving and revising these critical component over 2 decades, including issuing multiple recalls - are you saying that APR coils are as reliable As the factory component? How many hours have these been tested and what reliability data can you supply to support your claim that they produce a more consistent spark?
My electrical knowledge is not great and I have not messed with Dwell since setting timing on points with a Dwell meter. What is the range of Dwell on a running 2.0T? Does is change with RPM? Does this make the larger output at higher Dwell work only at certain rpm?
Increasing output on coils has not had any detrimental effect on older VW models, it's a great upgrade on a tuned car. I have the R8 coils on my B5 and cold starts are much better. 10% should be well within the standards of the plugs, I've had no issues with them in the 4 years I've had them on my car and have not seen anyone who has had issues.
Has anyone installed these on their Arteon yet? Any feedback on noticeable difference over stock as a stand alone, or would this be better suited to compound with other mods?
To bad these won’t apply to my 2015 CC with Gen II 2.0. With 25+/- PSI boost and all the mods I have done, it would be worth a try at only $35 a piece.
FYI - Nology makes a plug wire with an internal capacitor. There is a ground wire for every plug wire. Not available for TSI engine. EVERY forum will have an electrical engineer come on board and tell you just why these Nology wires can’t possibly help performance, gas mileage, etc., etc. So I bought a set. With my 13.2:1 compression race AMC 390 engine which peaked at 534 HP, compared to new MSD plug wires, I picked up an average of around 1.2 HP, which isn’t horrible in the class I race (with many restrictions; NHRA Stock Eliminator). However, from around 6,400 RPM to 7,200 RPM, there was a 12 HP gain. That’s out of this world. Unfortunately, the engine was shifted at only 6,800 due to this and that, mainly the small carb that was required was choking. I spoke to 3 other guys around the country and all said they had the exact same results. The 305 CID Trans Am racer had best results as he was at high RPM for longer periods of time on the straights and it did reduce his lap times.
If they were available, I would try them. Wouldn’t be the first time I wasted money in search of power!
