If you have a Subaru WRX or STI, you likely already know about IAG Performance. The company got its start selling used performance cars, but customers started requesting services related to their Subaru models. For more than a decade IAG has developed a line of performance parts for Subarus that has become synonymous with quality.

At Modern Automotive Performance, we’ve put plenty of IAG performance parts to the test, and they never let us down. We’re proud to partner with them and offer their line of parts for our Subaru-driving customers.

From single parts to full kits, our line of IAG Performance parts fills a variety of needs. Looking for a unique look for your taillights? The RockBlocker line of taillight overlay kits adds a sleek look that’s perfect for showing your tail off. For your engine, we have a number of air-oil separators, oil dipsticks, fuel rails, fluid caps, battery tiedowns and lines, many that come in color options to match the rest of your vehicle. And for those looking for an engine overhaul, their short blocks and case halves are some of the best in the business.

Our staff of gearheads has spent countless hours in the garage and on the track with these parts. Give us a call with your pickiest, most detailed questions, and we’ll steer you in the right direction for parts that will make your Subaru sing. You’ll also love our big-time discounts, shipping options and our fast response time — if your order is in stock, we start packing it as soon as we get it.

We’ve earned an industry-leading reputation for customer service, and we can’t wait to put that to work for you. Get started browsing through our collection of IAG Performance parts, and let us help bring all of your plans for your Subaru to life.
