2018-2023 Subaru WRX Turbo Sump Restrictor by Perrin
Many people experience oil burning issues or blue smoke from the exhaust. This problem can worsen after installing a cat-back, J-pipe, or turbo-back exhaust system. Installing these parts changes the exhaust pressure, which can cause engine oil to leak past the turbo seals, leading to a burnt oil smell and blue smoke. The Perrin Turbo Sump Restrictor solves this problem immediately.
The Perrin Turbo Sump Restrictor helps the turbo sump pump scavenge oil from the turbo sump more effectively. This creates a slight vacuum in the turbo sump, creating the proper balance between exhaust pressure and the vacuum at the turbo seals, significantly reducing the amount of leakage around the turbo seals. This does not change the oil flow to the turbo or cause any wear.
Perrin's plug-and-play sump pump restrictor is designed to make installation quick and easy, as it does not require cutting any hoses.
The turbo sump restrictor does not require any adjustments or modifications to function properly. They are designed to work right out of the box, performing optimally without any fine-tuning or changes.

Before you order
〇 Regarding import consumption tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of fitment
Our entire product database is based on North American (USDM) vehicles, so please check whether the product can be installed on a Japanese (JDM) vehicle before placing your order. (Please feel free to contact us if you are unsure whether a listed product fits your vehicle; our support team will investigate for you.)
If you place an order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model on our top page tabs, this does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding delivery
Shipping costs are paid at the time of settlement. Regarding shipping estimates, they will be calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air. They are never shipped by sea freight.
○ Regarding Japanese vehicle inspection compliance
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation sheets or similar documents for Japanese inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be delivery damage to the packaging or the product. We will handle returns, refunds, or exchanges only if you contact us within 7 days of receipt regarding products with delivery damage, defective products, or items different from what you ordered. Please understand that for products sold through us, we will handle warranty matters "only through us." Please note that we do not handle matters through other companies or distributors located within Japan.
